Module ascii 

Operations on ASCII [u8].

Structs

EscapeAscii

An iterator over the escaped version of a byte slice.

EscapeByte 🔒

SplitAsciiWhitespaceExperimental

An iterator over the non-ASCII-whitespace subslices of a byte slice, separated by any amount of ASCII whitespace.

Constants

SSE2_CHUNK_SIZE 🔒 x86-64 and sse2

Chunk size for SSE2 vectorized ASCII checking (4x 16-byte loads).

Functions

is_ascii 🔒 AArch64 and neon, or x86-64 and sse2

Uses explicit SIMD intrinsics to prevent LLVM from auto-vectorizing with broken code (e.g., AVX-512 on x86-64 that extracts mask bits one-by-one).

is_ascii_sse2 🔒 x86-64 and sse2

is_ascii_simple 👻 Experimental

ASCII test without the chunk-at-a-time optimizations.
