Struct core::arch::wasm64::v128

#[repr(simd)]
pub struct v128(_, _, _, _);

This is supported on WebAssembly only.

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 analogous to the v128 type in WebAssembly. Operations on v128 can only be performed with the functions in this module.
