Struct SourceFile 

pub struct SourceFile { /* private fields */ }

A single source file, with a precomputed index of where each line starts.

Implementations

impl SourceFile

pub fn name(&self) -> &str

pub fn text(&self) -> &str

pub fn line_count(&self) -> u32

pub fn location(&self, offset: u32) -> Location

Resolves a byte offset to a one based line and column.

Offsets past the end of the file clamp to the last position, so a diagnostic about unexpected end of input still renders somewhere sane.

pub fn line_text(&self, line: u32) -> &str

The text of a one based line, without its trailing newline.

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