pub bits: u64,
}
Expand description
Represents a set of “small characters”, those with Unicode scalar values less than 64.
This is stored as a bitmap, with 1 bit for each value.

Implementations§
source§impl SmallCharSet
impl SmallCharSet
sourcepub fn nonmember_prefix_len(&self, buf: &str) -> u32
pub fn nonmember_prefix_len(&self, buf: &str) -> u32
Count the number of bytes of characters at the beginning of buf
which are not in the set.
This functionality is used in BufferQueue::pop_except_from
.
Examples
let set = small_char_set!(48 49 50); // '0' '1' '2'
// `test` is 4 chars, 😁 is 4 chars, then we meet a character in the set
let test_str = "test😁01232afd";
assert_eq!(set.nonmember_prefix_len(test_str), 8);
