Struct Source 

pub struct Source { /* private fields */ }

Source text addressed by UTF-16 code units, as JavaScript strings are.

Implementations

impl Source

pub fn new(text: &str) -> Self

pub const fn len(&self) -> usize

pub const fn is_empty(&self) -> bool

pub fn units(&self) -> &[u16]

pub fn at(&self, index: usize) -> Option<u16>

The code unit at index, if any.

pub fn char_at(&self, index: usize) -> Option<char>

The code unit at index as a character; lone surrogates are None.

pub fn is_char(&self, index: usize, ch: char) -> bool

True when the unit at index is the ASCII or BMP character ch.

pub fn starts_with(&self, pattern: &str, index: usize) -> bool

pub fn slice(&self, start: usize, end: usize) -> String

source.slice(start, end), clamped like JavaScript’s.

pub fn index_of(&self, pattern: &str, from: usize) -> Option<usize>

source.indexOf(pattern, from).

pub fn code_point_text(&self, index: usize) -> String

String.fromCodePoint(source.codePointAt(index)): the whole character when index starts a surrogate pair.
