pub unsafe fn v128_load8_lane<const L: usize>(v: v128, m: *const u8) -> v128
Available on target_family="wasm" and target feature simd128 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).


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.
