Function core::arch::wasm64::v128_load8_lane
1.54.0 · source · pub unsafe fn v128_load8_lane<const L: usize>(v: v128, m: *const u8) -> v128
Available on
target_family="wasm"
and target feature simd128
and WebAssembly only.Expand description
Loads an 8-bit value from m
and sets lane L
of v
to that value.
This intrinsic is provided for completeness and is equivalent to
u8x16_replace_lane::<L>(v, *m)
(which doesn’t require unsafe
).
§Unsafety
This intrinsic is unsafe because it takes a raw pointer as an argument, and the pointer must be valid to load 1 byte from. Note that there is no alignment requirement on this pointer since this intrinsic performs a 1-aligned load.
