}

Source location information for AST nodes

Fields

column: usize

start_byte: usize

end_byte: usize

Implementations

impl SourceLocation

pub fn new( line: usize, column: usize, start_byte: usize, end_byte: usize, ) -> Self

pub fn as_str<'a>(&self, source: &'a [u8]) -> Option<&'a str>

Extract the source text for this location

pub fn find_line_bounds(&self, source: &[u8]) -> (usize, usize)

Find the start and end byte positions of the line containing this location Returns (line_start_byte, line_end_byte) including the newline If the previous line is empty (only whitespace), includes it too

pub fn find_line_bounds_with_following_blank( &self, source: &[u8], ) -> (usize, usize)

Find the start and end byte positions of the line containing this location, including any following blank line Returns (line_start_byte, line_end_byte) including newlines

pub fn extract_line_indentation(&self, source: &[u8]) -> String

Extract indentation (leading whitespace) from the line containing this location. Returns all leading spaces/tabs from the start of the line.

pub fn extract_indentation(&self, source: &[u8]) -> String

Extract indentation (leading whitespace) up to this location Returns the spaces/tabs from line start up to (but not past) the location

pub fn find_semicolon_end(&self, source: &[u8]) -> usize

Scan forward from end_byte through whitespace to find a ; and return the byte position immediately after it. Returns end_byte unchanged if no semicolon is found within a short distance.

pub fn find_braces_around(start: usize, source: &[u8]) -> (usize, usize)

Find braces surrounding a range in the source Returns (opening_brace_pos, closing_brace_pos) using depth tracking to find matching braces
