Constants

ALU_ALIGNMENT

ALU_ALIGNMENT_MASK

ALU_STRIDE_SIZE

Safety invariant: this is the amount of bytes consumed by unpack_alu. This will be twice the pointer width, as it consumes two usizes. This is also the number of bytes produced by pack_alu. This is also the number of u16 code units produced/consumed by unpack_alu/pack_alu respectively.

ASCII_MASK

BASIC_LATIN_MASK

MAX_STRIDE_SIZE

Functions

ascii_to_ascii^⚠

Safety: src and dst must have len elements, src is valid for read, dst is valid for write Safety-usable invariant: will return Some() when it fails to convert. The first value will be a u8 that is > 127.

ascii_to_ascii_stride 🔒 ^⚠

ascii_to_basic_latin^⚠

Safety: src and dst must have len elements, src is valid for read, dst is valid for write Safety-usable invariant: will return Some() when it fails to convert. The first value will be a u8 that is > 127.

ascii_to_basic_latin_stride_alu 🔒 ^⚠

ascii_valid_up_to

basic_latin_to_ascii^⚠

Safety: src and dst must have len elements, src is valid for read, dst is valid for write Safety-usable invariant: will return Some() when it fails to convert. The first value will be a u8 that is > 127.

basic_latin_to_ascii_stride_alu 🔒 ^⚠

count_zeros 🔒

find_non_ascii 🔒

iso_2022_jp_ascii_valid_up_to

likely 🔒

pack_alu 🔒 ^⚠

Safety: dst must point to valid space for writing two usizes

pack_latin1^⚠

Safety: src and dst must have len elements, src is valid for read, dst is valid for write

pack_latin1_stride_alu 🔒 ^⚠

unlikely 🔒

unpack_alu 🔒 ^⚠

Safety: dst must point to valid space for writing four usizes

unpack_latin1^⚠

Safety: src and dst must have len elements, src is valid for read, dst is valid for write

unpack_latin1_stride_alu 🔒 ^⚠

validate_ascii

Safety-usable invariant: will return Some() when it encounters non-ASCII, with the first element in the Some being guaranteed to be non-ASCII (> 127), and the second being the offset where it is found

validate_ascii_stride 🔒 ^⚠

Safety: src must be valid for the reads of two usizes
