Struct lrlex::DefaultLexeme

pub struct DefaultLexeme<StorageT: Debug = u32> { /* fields omitted */ }

lrlex’s standard lexeme struct: all lexemes are instances of this struct.

Trait Implementations

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

fn clone(&self) -> DefaultLexeme<StorageT>

Returns a copy of the value.

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

Performs copy-assignment from source.

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

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

Formats the value using the given formatter.

impl<StorageT: Copy + Debug + Eq + Hash> Display for DefaultLexeme<StorageT>

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

Formats the value using the given formatter.

impl<StorageT: Copy + Debug + Eq + Hash> Error for DefaultLexeme<StorageT>

fn source(&self) -> Option<&(dyn Error + 'static)>

The lower-level source of this error, if any.

fn backtrace(&self) -> Option<&Backtrace>

🔬 This is a nightly-only experimental API. (backtrace)

Returns a stack backtrace, if available, of where this error occurred.

fn description(&self) -> &str

👎 Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎 Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

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

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H) where
    H: Hasher, 

Feeds a slice of this type into the given Hasher.

impl<StorageT: Copy + Debug + Hash + Eq> Lexeme<StorageT> for DefaultLexeme<StorageT>

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.

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

Create a new faulty lexeme with ID tok_id and a starting position in the input start.

fn tok_id(&self) -> StorageT

The token ID.

fn span(&self) -> Span

Obtain this Lexeme’s Span.

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.

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

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

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

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

This method tests for !=.
