pattern
)Expand description
Associated type for <char as Pattern<'a>>::Searcher
.
Fields
haystack: &'a str
pattern
)finger: usize
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
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
pattern
)The character being searched for
utf8_size: usize
pattern
)The number of bytes needle
takes up when encoded in utf8.
utf8_encoded: [u8; 4]
pattern
)A utf8 encoded copy of the needle
