Expand description
Portable SIMD module.
This module offers a portable abstraction for SIMD operations that is not bound to any particular hardware architecture.
Macros
Constructs a new vector by selecting values from the lanes of the source vector or vectors to use.
Structs
A type representing a vector lane count.
A SIMD vector mask for LANES elements of width specified by Element.
A SIMD vector of LANES elements of type T.
Enums
An index into one of two vectors.
Traits
Marker trait for types that may be used as SIMD mask elements.
Marker trait for types that may be used as SIMD vector elements.
SAFETY: This trait, when implemented, asserts the compiler can monomorphize
#[repr(simd)] structs with the marked type as an element.
Strictly, it is valid to impl if the vector will not be miscompiled.
Practically, it is user-unfriendly to impl it if the vector won’t compile,
even when no soundness guarantees are broken by allowing the user to try.
This trait provides a possibly-temporary implementation of float functions
that may, in the absence of hardware support, canonicalize to calling an
operating system’s math.h dynamically-loaded library (also known as a
shared object). As these conditionally require runtime support, they
should only appear in binaries built assuming OS support: std.
Helper trait for vector lane counts.
Create a vector from the elements of another vector.
Create a vector from the elements of two other vectors.
