Struct SourceMap 

pub struct SourceMap {
    pub base_uri: String,
    pub text: String,
    pub line_starts: Vec<usize>,
}

Per-document source mapping for line/column resolution

Owns the source text buffer and line start index. Use build_line_starts() to construct the line index once.

Fields

base_uri: String

text: String

line_starts: Vec<usize>

Implementations

impl SourceMap

pub fn new(base_uri: String, text: String) -> Self

Create a new source map from source text

pub fn locate(&self, offset: usize) -> SourceLocation

Convert byte offset to line/column location

Returns 1-based line and column numbers. Column is counted in UTF-8 characters, not bytes.

pub fn get_text(&self, span: &SourceSpan) -> Option<&str>

Get source text for a span (returns None if span invalid)

pub fn into_compact(self) -> CompactSourceMap

Convert to compact source map (drops text, keeps line_starts)

Trait Implementations

impl Clone for SourceMap

fn clone(&self) -> SourceMap

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SourceMap

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

Formats the value using the given formatter.
