Primitive Type isize1.0.0[−]
Expand description
The pointer-sized signed integer type.
The size of this primitive is how many bytes it takes to reference any location in memory. For example, on a 32 bit target, this is 4 bytes and on a 64 bit target, this is 8 bytes.
Implementations
Converts a string slice in a given base to an integer.
The string is expected to be an optional +
or -
sign followed by digits.
Leading and trailing whitespace represent an error. Digits are a subset of these characters,
depending on radix
:
0-9
a-z
A-Z
Panics
This function panics if radix
is not in the range from 2 to 36.
Examples
Basic usage:
assert_eq!(isize::from_str_radix("A", 16), Ok(10));
RunShifts the bits to the right by a specified amount, n
,
wrapping the truncated bits to the beginning of the resulting
integer.
Please note this isn’t the same operation as the >>
shifting operator!
Examples
Basic usage:
let n = 0x6e10aaisize;
let m = 0xaa00000000006e1;
assert_eq!(n.rotate_right(12), m);
RunReverses the order of bits in the integer. The least significant bit becomes the most significant bit, second least-significant bit becomes second most-significant bit, etc.
Examples
Basic usage:
let n = 0x1234567890123456isize;
let m = n.reverse_bits();
assert_eq!(m, 0x6a2c48091e6a2c48);
assert_eq!(0, 0isize.reverse_bits());
RunConverts an integer from big endian to the target’s endianness.
On big endian this is a no-op. On little endian the bytes are swapped.
Examples
Basic usage:
let n = 0x1Aisize;
if cfg!(target_endian = "big") {
assert_eq!(isize::from_be(n), n)
} else {
assert_eq!(isize::from_be(n), n.swap_bytes())
}
RunConverts an integer from little endian to the target’s endianness.
On little endian this is a no-op. On big endian the bytes are swapped.
Examples
Basic usage:
let n = 0x1Aisize;
if cfg!(target_endian = "little") {
assert_eq!(isize::from_le(n), n)
} else {
assert_eq!(isize::from_le(n), n.swap_bytes())
}
RunUnchecked integer addition. Computes self + rhs
, assuming overflow
cannot occur.
Safety
This results in undefined behavior when
self + rhs > isize::MAX
or self + rhs < isize::MIN
,
i.e. when checked_add
would return None
.
Unchecked integer subtraction. Computes self - rhs
, assuming overflow
cannot occur.
Safety
This results in undefined behavior when
self - rhs > isize::MAX
or self - rhs < isize::MIN
,
i.e. when checked_sub
would return None
.
Unchecked integer multiplication. Computes self * rhs
, assuming overflow
cannot occur.
Safety
This results in undefined behavior when
self * rhs > isize::MAX
or self * rhs < isize::MIN
,
i.e. when checked_mul
would return None
.
Checked Euclidean division. Computes self.div_euclid(rhs)
,
returning None
if rhs == 0
or the division results in overflow.
Examples
Basic usage:
assert_eq!((isize::MIN + 1).checked_div_euclid(-1), Some(9223372036854775807));
assert_eq!(isize::MIN.checked_div_euclid(-1), None);
assert_eq!((1isize).checked_div_euclid(0), None);
RunChecked Euclidean remainder. Computes self.rem_euclid(rhs)

assert_eq!(5isize.checked_rem_euclid(0), None);
assert_eq!(isize::MIN.checked_rem_euclid(-1), None);
RunUnchecked shift left. Computes self << rhs
, assuming that
rhs
is less than the number of bits in self
.
Safety
This results in undefined behavior if rhs
is larger than
or equal to the number of bits in self
,
i.e. when checked_shl
would return None
.
Unchecked shift right. Computes self >> rhs
, assuming that
rhs
is less than the number of bits in self
.
Safety
This results in undefined behavior if rhs
is larger than
or equal to the number of bits in self
,
i.e. when checked_shr
would return None
.

, returning MAX
if self == MIN
instead of overflowing.

numeric bounds instead of overflowing.
Examples

assert_eq!(isize::MAX.saturating_div(-1), isize::MIN + 1);
assert_eq!(isize::MIN.saturating_div(-1), isize::MAX);
Runlet _ = 1isize.saturating_div(0);
RunWrapping (modular) division. Computes self / rhs
, wrapping around at the
boundary of the type.
The only case where such wrapping can occur is when one divides MIN / -1
on a signed type (where
MIN
is the negative minimal value for the type); this is equivalent to -MIN
, a positive value
that is too large to represent in the type. In such a case, this function returns MIN
itself.
Panics
This function will panic if rhs
is 0.
Examples
Basic usage:
assert_eq!(100isize.wrapping_div(10), 10);
assert_eq!((-128i8).wrapping_div(-1), -128);
RunWrapping Euclidean division. Computes self.div_euclid(rhs)
,
wrapping around at the boundary of the type.
Wrapping will only occur in MIN / -1
on a signed type (where MIN
is the negative minimal value
for the type). This is equivalent to -MIN
, a positive value that is too large to represent in the
type. In this case, this method returns MIN
itself.
Panics
This function will panic if rhs
is 0.
Examples
Basic usage:
assert_eq!(100isize.wrapping_div_euclid(10), 10);
assert_eq!((-128i8).wrapping_div_euclid(-1), -128);
RunWrapping (modular) remainder. Computes self % rhs
, wrapping around at the
boundary of the type.
Such wrap-around never actually occurs mathematically; implementation artifacts make x % y
invalid for MIN / -1
on a signed type (where MIN
is the negative minimal value). In such a case,
this function returns 0
.
Panics
This function will panic if rhs
is 0.
Examples
Basic usage:
assert_eq!(100isize.wrapping_rem(10), 0);
assert_eq!((-128i8).wrapping_rem(-1), 0);
RunWrapping Euclidean remainder. Computes self.rem_euclid(rhs)
, wrapping around
at the boundary of the type.
Wrapping will only occur in MIN % -1
on a signed type (where MIN
is the negative minimal value
for the type). In this case, this method returns 0.
Panics
This function will panic if rhs
is 0.
Examples
Basic usage:
assert_eq!(100isize.wrapping_rem_euclid(10), 0);
assert_eq!((-128i8).wrapping_rem_euclid(-1), 0);
RunWrapping (modular) negation. Computes -self
, wrapping around at the boundary
of the type.
The only case where such wrapping can occur is when one negates MIN
on a signed type (where MIN
is the negative minimal value for the type); this is a positive value that is too large to represent
in the type. In such a case, this function returns MIN
itself.
Examples
Basic usage:
assert_eq!(100isize.wrapping_neg(), -100);
assert_eq!(isize::MIN.wrapping_neg(), isize::MIN);
RunPanic-free bitwise shift-left; yields self << mask(rhs)
, where mask
removes
any high-order bits of rhs
that would cause the shift to exceed the bitwidth of the type.
Note that this is not the same as a rotate-left; the RHS of a wrapping shift-left is restricted to
the range of the type, rather than the bits shifted out of the LHS being returned to the other end.
The primitive integer types all implement a rotate_left
function,
which may be what you want instead.
Examples
Basic usage:
assert_eq!((-1isize).wrapping_shl(7), -128);
assert_eq!((-1isize).wrapping_shl(128), -1);
RunPanic-free bitwise shift-right; yields self >> mask(rhs)
, where mask
removes any high-order bits of rhs
that would cause the shift to exceed the bitwidth of the type.
Note that this is not the same as a rotate-right; the RHS of a wrapping shift-right is restricted
to the range of the type, rather than the bits shifted out of the LHS being returned to the other
end. The primitive integer types all implement a rotate_right
function,
which may be what you want instead.
Examples
Basic usage:
assert_eq!((-128isize).wrapping_shr(7), -1);
assert_eq!((-128i16).wrapping_shr(64), -128);
RunWrapping (modular) absolute value. Computes self.abs()
, wrapping around at
the boundary of the type.
The only case where such wrapping can occur is when one takes the absolute value of the negative
minimal value for the type; this is a positive value that is too large to represent in the type. In
such a case, this function returns MIN
itself.
Examples
Basic usage:
assert_eq!(100isize.wrapping_abs(), 100);
assert_eq!((-100isize).wrapping_abs(), 100);
assert_eq!(isize::MIN.wrapping_abs(), isize::MIN);
assert_eq!((-128i8).wrapping_abs() as u8, 128);

if self < 0
, this is equal to round towards +/- infinity.

.
This is done as if by the Euclidean division algorithm – given
r = self.rem_euclid(rhs)
, self = rhs * self.div_euclid(rhs) + r
, and
0 <= r < abs(rhs)
.
Panics

is 0 or the division results in overflow.

log2
can produce results more efficiently for base 2, and log10
can produce results more efficiently for base 10.
Panics
When the number is zero, or if the base is not at least 2; it panics in debug mode and the return value is 0 in release mode.
Examples
#![feature(int_log)]
assert_eq!(5isize.log(5), 1);
RunReturns the logarithm of the number with respect to an arbitrary base, rounded down.
Returns None
if the number is negative or zero, or if the base is not at least 2.
This method might not be optimized owing to implementation details;
checked_log2
can produce results more efficiently for base 2, and
checked_log10
can produce results more efficiently for base 10.
Examples
#![feature(int_log)]
assert_eq!(5isize.checked_log(5), Some(1));
RunComputes the absolute value of self
.
Overflow behavior
The absolute value of
isize::MIN
cannot be represented as an
isize
,
and attempting to calculate it will cause an overflow. This means
that code in debug mode will trigger a panic on this case and
optimized code will return
isize::MIN
without a panic.

assert_eq!((-10isize).abs(), 10);

RunReturn the memory representation of this integer as a byte array in native byte order.

RunWhen starting from a slice rather than an array, fallible conversion APIs can be used:
use std::convert::TryInto;
fn read_ne_isize(input: &mut &[u8]) -> isize {
let (int_bytes, rest) = input.split_at(std::mem::size_of::<isize>());
*input = rest;
isize::from_ne_bytes(int_bytes.try_into().unwrap())
}
Run👎 Deprecating in a future Rust version: replaced by the MIN
associated constant on this type
replaced by the MIN
associated constant on this type
New code should prefer to use
isize::MIN
instead.
Returns the smallest value that can be represented by this integer type.
👎 Deprecating in a future Rust version: replaced by the MAX
associated constant on this type
replaced by the MAX
associated constant on this type
New code should prefer to use
isize::MAX
instead.
Returns the largest value that can be represented by this integer type.
