Struct SourceRegistry 

pub struct SourceRegistry { /* private fields */ }

A store mapping each SourceId to its raw source bytes.

Lets diagnostics and lossless codecs recover original text by Origin.

Implementations

impl SourceRegistry

pub fn insert( &mut self, source: SourceId, bytes: Arc<[u8]>, ) -> Option<Arc<[u8]>>

Inserts source bytes, returning any previous bytes for the same id.

pub fn intern_bytes(&mut self, source: SourceId, bytes: impl Into<Arc<[u8]>>)

Interns raw bytes under source, replacing any prior entry.

pub fn intern_text(&mut self, source: SourceId, text: &str)

Interns text under source as its UTF-8 bytes.

pub fn intern_span(&mut self, origin: &Origin, bytes: &[u8])

Splices bytes into the stored source at the origin’s span.

pub fn get(&self, source: &SourceId) -> Option<&Arc<[u8]>>

Returns the stored bytes for source, if any.

pub fn slice(&self, origin: &Origin) -> Option<&[u8]>

Returns the byte slice covered by origin’s span, if available.
