Struct Source 

pub struct Source { /* private fields */ }

Primarily used to map spans (0 based character index ranges) to bytes.

Implementations

impl Source

pub fn from_file(path: impl Into<PathBuf>) -> Result<Self>

pub fn path(&self) -> Option<&PathBuf>

pub fn text(&self) -> &str

pub fn span(&self) -> Span

pub fn range(&self, span: Span) -> Range<usize>

Resolves the given span into a byte index range.

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

Gets a sub span of source text from the file.

pub fn location(&self, i: usize) -> Location

Resolves a global character index within this file into a 0-based Location.

pub fn byte(&self, i: usize) -> usize

Returns the UTF-8 byte index corresponding to a global character index.

impl Debug for Source

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

Formats the value using the given formatter.

impl Default for Source

fn default() -> Self
