Module simd 

Vectorized SIMD implementations for x86_64 (AVX2).

Functions

decode_avx2^⚠

Decodes 32 Base64 ASCII bytes to 24 raw bytes using AVX2. Returns (input_bytes_consumed, output_bytes_written). Breaks out if padding (‘=’) or invalid characters are encountered.

decode_avx512^⚠

Decodes 64 Base64 ASCII bytes to 48 raw bytes using AVX-512BW. Returns (input_bytes_consumed, output_bytes_written).

decode_ssse3^⚠

Decodes 16 Base64 ASCII bytes to 12 raw bytes using SSSE3 (128-bit SIMD).

encode_avx2^⚠

Encodes 24 bytes to 32 Base64 ASCII bytes using AVX2. Returns (input_bytes_consumed, output_bytes_written).

encode_avx512^⚠

Encodes 48 bytes to 64 Base64 ASCII bytes using AVX-512BW. Returns (input_bytes_consumed, output_bytes_written).

encode_ssse3^⚠

Encodes 12 bytes to 16 Base64 ASCII bytes using SSSE3 (128-bit SIMD).

has_avx2

Checks if the host x86_64 CPU supports AVX2.

has_avx512

Checks if the host x86_64 CPU supports AVX-512 (specifically AVX-512F and AVX-512BW).

has_neon

Checks if the host CPU supports ARM NEON (always true on AArch64).

has_ssse3

Checks if the host x86_64 CPU supports SSSE3.

has_wasm_simd128

Checks if the host CPU supports WebAssembly 128-bit SIMD.
