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

A SIMD mask with 16 elements for vectors with 64-bit 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 `[i64; 16]`.
