Struct SourceFile 

pub struct SourceFile {
    pub id: FileId,
    pub name: String,
    pub src: String,
    /* private fields */
}

Information about a source file.

Fields

id: FileId

The file ID.

name: String

The file name or path.

src: String

The source code content.

Implementations

impl SourceFile

pub fn new(id: FileId, name: String, src: String) -> Self

Create a new source file.

pub fn lookup_line_col(&self, pos: BytePos) -> LineCol

Get the line/column for a byte position.

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

Get the 0-indexed line number for a byte position.

pub fn source_text(&self, span: Span) -> &str

Get the source text for a span.

pub fn num_lines(&self) -> usize

Get the number of lines in the file.

pub fn line_content(&self, line_idx: usize) -> Option<&str>

Get the content of a specific line (0-indexed).

pub fn line_start(&self, line_idx: usize) -> Option<BytePos>

Get the byte offset of the start of a line (0-indexed).

pub fn span_lines(&self, span: Span) -> SpanLines

Get span information for rendering: start line, start col, end line, end col.

Note: Spans are half-open [lo, hi), so the end position is computed from the last included byte (hi - 1) for non-empty spans.

fn clone(&self) -> SourceFile

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SourceFile

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