Struct CapturedTokenTree 

pub struct CapturedTokenTree { /* private fields */ }

One captured token: what it carries, where it sits, and how to reach the compiler span it came from.

Implementations

impl CapturedTokenTree

pub fn group_fragment( &self, expected: CapturedDelimiter, ) -> Option<CapturedFragment<'_>>

Borrow this token’s grouped members as one exact fragment when its delimiter matches.

impl CapturedTokenTree

pub const fn payload(&self) -> &CapturedPayload

What this token carries.

pub const fn path(&self) -> &TokenPath

The route from the root of the declared input to this token.

pub const fn span(&self) -> SpanHandle

The handle into the producer’s span table.

pub fn word(&self) -> Option<&str>

The word this token spells, where it is a word.

pub const fn punct(&self) -> Option<char>

The punctuation character this token spells, whether it stands alone or joins what follows.

pub fn raw_identifier(&self) -> Option<&str>

The raw identifier’s name without its r# marker, where this is one.

pub const fn joint_punct(&self) -> Option<char>

The punctuation character joined to what follows, where this is one.

pub fn text(&self) -> Option<&str>

The text this token carries, where it is a text literal.

The text and never the spelling, so a raw text answers here on the same terms as a quoted one and the escape a quoted one carried is already read.

Nonclaims

A byte string, a C string, a character, and a byte are not text and do not answer here; each is a different value at the seat it is written to, and a road wanting one asks for it by name.

pub fn number(&self) -> Option<&str>

The numeric spelling this token carries, where it is a numeric literal.

The spelling exactly as written — the base, the digit separators, and the suffix are part of what the declaration says — so a grammar wanting a value states which spellings it reads and refuses the rest itself.

pub fn group(&self) -> Option<(CapturedDelimiter, &[Self])>

The group this token opens, where it is one.
