Module std::simd

🔬This is a nightly-only experimental API. (portable_simd #86656)

Portable SIMD module.

This module offers a portable abstraction for SIMD operations that is not bound to any particular hardware architecture.

Macros

• simd_swizzleExperimental
  Constructs a new SIMD vector by copying elements from selected lanes in other vectors.

Structs

• LaneCountExperimental
  Specifies the number of lanes in a SIMD vector as a type.
• MaskExperimental
  A SIMD vector mask for LANES elements of width specified by Element.
• SimdExperimental
  A SIMD vector with the shape of [T; N] but the operations of T.

Enums

• WhichExperimental
  Specifies a lane index into one of two SIMD vectors.

Traits

• MaskElementExperimental
  Marker trait for types that may be used as SIMD mask elements.
• SimdCastExperimental
  Supporting trait for Simd::cast. Typically doesn’t need to be used directly.
• SimdCastPtrExperimental
  Supporting trait for Simd::cast_ptr. Typically doesn’t need to be used directly.
• SimdConstPtrExperimental
  Operations on SIMD vectors of constant pointers.
• SimdElementExperimental
  Marker trait for types that may be used as SIMD vector elements.
• SimdFloatExperimental
  Operations on SIMD vectors of floats.
• SimdIntExperimental
  Operations on SIMD vectors of signed integers.
• SimdMutPtrExperimental
  Operations on SIMD vectors of mutable pointers.
• SimdOrdExperimental
  Parallel Ord.
• SimdPartialEqExperimental
  Parallel PartialEq.
• SimdPartialOrdExperimental
  Parallel PartialOrd.
• SimdUintExperimental
  Operations on SIMD vectors of unsigned integers.
• StdFloatExperimental
  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.
• SupportedLaneCountExperimental
  Statically guarantees that a lane count is marked as supported.
• SwizzleExperimental
  Create a vector from the elements of another vector.
• Swizzle2Experimental
  Create a vector from the elements of two other vectors.
• ToBitMaskExperimental
  Converts masks to and from integer bitmasks.
