source§

fn new(tok_id: StorageT, start: usize, len: usize) -> Self

Create a new lexeme with ID tok_id, a starting position in the input start, and length len. Read more
source§

fn new_faulty(tok_id: StorageT, start: usize, len: usize) -> Self

fn tok_id(&self) -> StorageT

The token ID.
source§

fn span(&self) -> Span

Obtain this Lexeme’s Span.
source§

fn faulty(&self) -> bool

Returns true if this lexeme is “faulty” i.e. is the result of error recovery in some way. If true, note that the lexeme’s span may be greater or less than you may expect from the lexeme’s definition.
source§

impl<StorageT: PartialEq + Debug> PartialEq for DefaultLexeme<StorageT>

source§

fn eq(&self, other: &DefaultLexeme<StorageT>) -> bool

This method tests for self and other values to be equal, and is used by ==.
1.0.0 · source§

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
