Generic crate-internal routines for the memchr family of functions.

Structs

Iter 🔒

An iterator over all occurrences of a set of bytes in a haystack.

One 🔒

Finds all occurrences of a single byte in a haystack.

Three 🔒

Finds all occurrences of two bytes in a haystack.

Two 🔒

Functions

count_byte_by_byte 🔒 ^⚠

Performs a forward byte-at-a-time loop until ptr >= end_ptr and returns the number of times confirm(*ptr) returns true.

fwd_byte_by_byte 🔒 ^⚠

Performs a forward byte-at-a-time loop until either ptr >= end_ptr or until confirm(*ptr) returns true. If the former occurs, then None is returned. If the latter occurs, then the pointer at which confirm returns true is returned.

rev_byte_by_byte 🔒 ^⚠

Performs a reverse byte-at-a-time loop until either ptr < start_ptr or until confirm(*ptr) returns true. If the former occurs, then None is returned. If the latter occurs, then the pointer at which confirm returns true is returned.

search_slice_with_raw 🔒 ^⚠

Search a slice using a function that operates on raw pointers.
