Struct LineInfo

pub struct LineInfo<'a> {
    pub per_line: Vec<(u16, u16)>,
    source: &'a str,
    pub line_starts: Vec<usize>,
}

Fields

per_line: Vec<(u16, u16)>

Number of tokens on each line (run-length encoded) (line_number, tokens_on_line)

source: &'a str

line_starts: Vec<usize>

The starting position of each line in the source code

Implementations

impl LineInfo<'_>

pub fn new(source: &str) -> LineInfo<'_>

Creates a new LineInfo object

Arguments

• source - The source code string

Returns

A new LineInfo object with the line starts calculated

pub fn get_line_col(&self, pos: usize) -> (usize, usize)

Get the line and column number for a token position

Arguments

• pos - The position of the token in the source code

Returns

A tuple containing the line number and column number

pub fn get_line_text(&self, line: usize) -> Option<&str>

Get the text for a specific line

Arguments

• line - The line number to retrieve

Returns

The text of the line, or None if the line number is invalid
