// Required methods
fn select(self, mask: Self::Mask, default: Self) -> Self;

}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.
Required Associated Constants§
Required Associated Types§
Sourcetype Native: NativeType
type Native: NativeType
The NativeType of this struct. E.g. f32 for a NativeSimd = f32x16.
Sourcetype Mask: FromMaskChunk<Self::Chunk>
type Mask: FromMaskChunk<Self::Chunk>
Type used for masking.
Required Methods§
Sourcefn from_chunk(v: &[Self::Native]) -> Self
fn from_chunk(v: &[Self::Native]) -> Self
Sourcefn from_incomplete_chunk(v: &[Self::Native], remaining: Self::Native) -> Self
fn from_incomplete_chunk(v: &[Self::Native], remaining: Self::Native) -> Self
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.
Dyn Compatibility§
This trait is not dyn compatible.
In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
