Expand description

A struct that lends itself well to be compiled leveraging SIMD

Safety

The NativeType and the NativeSimd must have possible a matching alignment. e.g. slicing &[NativeType] by align_of<NativeSimd>() must be properly aligned/safe.

Associated Types

The NativeType of this struct. E.g. f32 for a NativeSimd = f32x16.

The type holding bits for masks.

Type used for masking.

Associated Constants

Number of lanes

Required methods

Sets values to default based on mask.

Convert itself from a slice.

Panics
  • iff v.len() != T::LANES

creates a new Self from v by populating items from v up to its length. Items from v at positions larger than the number of lanes are ignored; remaining items are populated with remaining.

Returns a tuple of 3 items whose middle item is itself, and the remaining are the head and tail of the un-aligned parts.
