Implementations

impl OptionList

pub fn text_range(&self) -> TextRange

Byte range covered by this option list in the source buffer.

pub fn line(&self) -> usize

Get the line number (0-indexed) where this node starts.

pub fn column(&self) -> usize

Get the column number (0-indexed, in bytes) where this node starts.

pub fn line_col(&self) -> (usize, usize)
