Struct ScannedSource 

pub struct ScannedSource { /* private fields */ }

The immutable product of one lexical pass over a source file.

It retains the file identity, the ScriptKind, the shared source text, the non-EOF tokens in lexical order (including trivia), and the terminal end-of-file token whose empty range anchors the end of the source.

Implementations

impl ScannedSource

pub const fn source_id(&self) -> SourceId

Returns the source this token stream describes.

pub const fn script_kind(&self) -> ScriptKind

Returns the syntax the source was scanned as.

pub fn source(&self) -> &Arc<SourceText>

Returns the shared, immutable source text.

pub fn source_text(&self) -> &SourceText

Returns the source text mapper directly.

pub fn tokens(&self) -> &[Token]

Returns the non-EOF tokens in lexical order, including trivia.

pub const fn eof(&self) -> &Token

Returns the terminal end-of-file token.

pub fn token_text(&self, token: &Token) -> Option<&str>

Returns the zero-copy lexeme for one token of this source.

None identifies a range that is not a valid UTF-16 slice of this file, which cannot arise from a scanner-produced token.

Trait Implementations

impl Clone for ScannedSource

fn clone(&self) -> ScannedSource

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

Performs copy-assignment from source.

impl Debug for ScannedSource

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