Struct markup5ever::SmallCharSet

pub struct SmallCharSet {
    pub bits: u64,
}

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.

Fields

bits: u64

Methods

impl SmallCharSet

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);

Trait Implementations

impl Debug for SmallCharSet

fn fmt(&self, __arg_0: &mut Formatter) -> Result

impl Hash for SmallCharSet

fn hash<__H: Hasher>(&self, __arg_0: &mut __H)

Feeds this value into the given [Hasher].

fn hash_slice<H>(data: &[Self], state: &mut H) where
    H: Hasher,
