Implementations

impl SourceLocation

pub fn new( line: usize, column: usize, start_byte: usize, end_byte: usize, source: Arc<Vec<u8>>, ) -> Self

pub fn with_byte_range(&self, start_byte: usize, end_byte: usize) -> Self

Create a new SourceLocation sharing the same source but pointing at a different byte range. Line/column are zeroed since they are only used for display and these synthetic locations are used for fix generation.

pub fn source(&self) -> &[u8]

Get the shared source bytes

pub fn as_str(&self) -> Option<&str>

Extract the source text for this location

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

Return (start, end) covering the full line from its first byte to just past the trailing newline — no blank-line absorption.

pub fn find_line_bounds(&self) -> (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) -> (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) -> 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) -> 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_after(&self, target: u8) -> usize

Scan forward from end_byte through whitespace to find target and return the byte position immediately after it. Returns end_byte unchanged if the target is not found before a non-whitespace byte.

pub fn find_before(&self, target: u8) -> usize

Scan backward from start_byte through whitespace to find target and return the byte position of the target. Returns start_byte unchanged if the target is not found before a non-whitespace byte.

pub fn find_semicolon_end(&self) -> usize

Convenience: scan forward for ; — equivalent to find_after(b';')

pub fn count_trailing_newlines(&self) -> usize

Count consecutive newlines immediately after end_byte.

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

Find braces surrounding this location in the source. Returns (opening_brace_pos, closing_brace_pos) using depth tracking to find matching braces.

Trait Implementations

impl Clone for SourceLocation

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for SourceLocation

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for SourceLocation

fn default() -> Self

Returns the “default value” for a type.

impl Serialize for SourceLocation

fn serialize<S: Serializer>(&self, s: S) -> Result<S::Ok, S::Error>

Serialize this value into the given Serde serializer.
