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
sourceimpl isize
impl isize
sourcepub fn from_str_radix(src: &str, radix: u32) -> Result<isize, ParseIntError>
pub fn from_str_radix(src: &str, radix: u32) -> Result<isize, ParseIntError>
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));

Wrapping (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

is 0.

Wrapping 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.

Wrapping (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
.

Panic-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.

Run1.13.0 (const: 1.32.0) · sourcepub const fn overflowing_abs(self) -> (isize, bool)
pub const fn overflowing_abs(self) -> (isize, bool)
Computes the absolute value of self
.
Returns a tuple of the absolute version of self along with a boolean indicating whether an overflow happened. If self is the minimum value (e.g., isize::MIN for values of type isize), then the minimum value will be returned again and true will be returned for an overflow happening.
Examples
Basic usage:
assert_eq!(10isize.overflowing_abs(), (10, false));
assert_eq!((-10isize).overflowing_abs(), (10, false));
assert_eq!((isize::MIN).overflowing_abs(), (isize::MIN, true));
Run1.38.0 (const: 1.52.0) · sourcepub const fn div_euclid(self, rhs: isize) -> isize
pub const fn div_euclid(self, rhs: isize) -> isize
Calculates the quotient of Euclidean division of self
by rhs
.
This computes the integer q
such that self = q * rhs + r
, with
r = self.rem_euclid(rhs)
and 0 <= r < abs(rhs)
.
In other words, the result is self / rhs
rounded to the integer q
such that self >= q * rhs
.
If self > 0
, this is equal to round towards zero (the default in Rust);
if self < 0
, this is equal to round towards +/- infinity.
Panics
This function will panic if rhs
is 0 or the division results in overflow.
Examples
Basic usage:
let a: isize = 7; // or any other integer type
let b = 4;
assert_eq!(a.div_euclid(b), 1); // 7 >= 4 * 1
assert_eq!(a.div_euclid(-b), -1); // 7 >= -4 * -1
assert_eq!((-a).div_euclid(b), -2); // -7 >= 4 * -2

Run1.38.0 (const: 1.52.0) · sourcepub const fn rem_euclid(self, rhs: isize) -> isize
pub const fn rem_euclid(self, rhs: isize) -> isize
Calculates the least nonnegative remainder of self (mod rhs)

, and
0 <= r < abs(rhs)
.
Panics

Runsourcepub const fn log(self, base: isize) -> u32
pub const fn log(self, base: isize) -> u32
Returns the logarithm of the number with respect to an arbitrary base, rounded down.
This method might not be optimized owing to implementation details;
log2

Computes the absolute value of self

Overflow behavior
The absolute value of

that code in debug mode will trigger a panic on this case and
optimized code will return
isize::MIN
without a panic.
