`pack4xI8`

Function

Packs the low byte of each component of a vec4i into a u32, four bytes in a word.

The signature and the sentence under each name are the compiler's own text at commit 26de7be8.

Syntax

declare function pack4xI8(a0: vec4i): u32
declare function pack4xI8(e: vec4i): u32

The result is unsigned even though the components are not; a component that does not fit is TRUNCATED, where pack4xI8Clamp saturates. WebGPU-only.
