Variants

Term

|term| (eclconceptreference, altidentifier).

String

A quoted string (typedsearchterm, timevalue, the quoted altidentifier, and the string concrete value).

AltIdentifier

scheme#code (altidentifier without quotes).

Integer

A run of digits (sctid, integervalue, nonnegativeintegervalue).

Identifier

A word: the keywords, refsetfieldname, languagecode, dialectalias, and the reverse flag R.

Implementations

impl Kind

pub const fn describe(self) -> &'static str

The token class as an error message names it.

Trait Implementations

impl Clone for Kind

fn clone(&self) -> Kind

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl ContainsToken<&Token<'_>> for Kind

fn contains_token(&self, token: &Token<'_>) -> bool

Returns true if self contains the token

impl Copy for Kind

impl Debug for Kind

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

Formats the value using the given formatter.

impl Eq for Kind

impl Hash for Kind

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, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<'s> Logos<'s> for Kind

type Error = ()

Error type returned by the lexer. This can be set using #[logos(error = MyError)]. Defaults to () if not set.

type Extras = ()

Associated type Extras for the particular lexer. This can be set using #[logos(extras = MyExtras)] and accessed inside callbacks.

type Source = str

Source type this token can be lexed from. This will default to str, unless one of the defined patterns explicitly uses non-unicode byte values or byte slices, in which case that implementation will use [u8].

fn lex( lex: &mut Lexer<'s, Self>, ) -> Option<Result<Self, <Self as Logos<'s>>::Error>>

The heart of Logos. Called by the Lexer. The implementation for this function is generated by the logos-derive crate.

fn lexer(source: &'source Self::Source) -> Lexer<'source, Self>

where Self::Extras: Default,

Create a new instance of a Lexer that will produce tokens implementing this Logos.

fn lexer_with_extras( source: &'source Self::Source, extras: Self::Extras, ) -> Lexer<'source, Self>

Create a new instance of a Lexer with the provided Extras that will produce tokens implementing this Logos.

impl PartialEq for Kind

fn eq(&self, other: &Kind) -> bool

Equality operator ==.

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

Inequality operator !=.

impl PartialEq<Kind> for Token<'_>

fn eq(&self, other: &Kind) -> bool

Equality operator ==.

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

Inequality operator !=.

impl StructuralPartialEq for Kind
