Trait TextMap

pub trait TextMap {
    // Required methods
    fn text(&self) -> &str;
    fn offset_to_pos(&self, offset: usize) -> Option<Pos>;
    fn line_range(&self, line: u32) -> Option<Range<Pos>>;
    fn substr(&self, range: Range<Pos>) -> Option<&str>;

    // Provided method
    fn offset_range_to_range(&self, offsets: Range<usize>) -> Option<Range<Pos>> { ... }
}

Defines operations to convert between byte offsets and native Pos.

Most operations return an Option where None signals that the conversion wasn’t successful.

Required Methods

fn text(&self) -> &str

fn offset_to_pos(&self, offset: usize) -> Option<Pos>

fn line_range(&self, line: u32) -> Option<Range<Pos>>

fn substr(&self, range: Range<Pos>) -> Option<&str>

Provided Methods

fn offset_range_to_range(&self, offsets: Range<usize>) -> Option<Range<Pos>>
