Struct text_unit::TextUnit

pub struct TextUnit(_);

An offset into text. Offset is represented as u32 storing number of utf8-bytes, but most of the clients should treat it like opaque measure.

Methods

impl TextUnit

pub fn of_char(c: char) -> TextUnit

TextUnit equal to the length of this char.

pub fn of_str(s: &str) -> TextUnit

TextUnit equal to the length of this string.

Panics

Panics if the length of the string is greater than u32::max_value()
