# Type Alias std::simd::prelude::masksizex32

source ·

    pub type masksizex32 = Mask<isize, 32>;

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

A SIMD mask with 32 elements for vectors with pointer-sized element types.

The layout of this type is unspecified, and may change between platforms and/or Rust versions, and code should not assume that it is equivalent to `[isize; 32]`.

## Aliased Type§
