Expand description

WASM-specific 128-bit wide SIMD vector type.

This type corresponds to the `v128` type in the WebAssembly SIMD proposal. This type is 128-bits large and the meaning of all the bits is defined within the context of how this value is used.

This same type is used simultaneously for all 128-bit-wide SIMD types, for example:

- sixteen 8-bit integers (both `i8` and `u8`)
- eight 16-bit integers (both `i16` and `u16`)
- four 32-bit integers (both `i32` and `u32`)
- two 64-bit integers (both `i64` and `u64`)
- four 32-bit floats (`f32`)
- two 64-bit floats (`f64`)

The `v128` type in Rust is intended to be quite analagous to the `v128` type in WebAssembly. Operations on `v128` can only be performed with the functions in this module.
