Expand description

Associated type for <char as Pattern<'a>>::Searcher.

Fields

haystack: &'a str
🔬 This is a nightly-only experimental API. (pattern)
finger: usize
🔬 This is a nightly-only experimental API. (pattern)

finger is the current byte index of the forward search. Imagine that it exists before the byte at its index, i.e. haystack[finger] is the first byte of the slice we must inspect during forward searching

finger_back: usize
🔬 This is a nightly-only experimental API. (pattern)

finger_back is the current byte index of the reverse search. Imagine that it exists after the byte at its index, i.e. haystack[finger_back - 1] is the last byte of the slice we must inspect during forward searching (and thus the first byte to be inspected when calling next_back()).

needle: char
🔬 This is a nightly-only experimental API. (pattern)

The character being searched for

utf8_size: usize
🔬 This is a nightly-only experimental API. (pattern)

The number of bytes needle takes up when encoded in utf8.

utf8_encoded: [u8; 4]
🔬 This is a nightly-only experimental API. (pattern)

A utf8 encoded copy of the needle
