Enum MultiStringToken 

pub enum MultiStringToken<'input> {
    Error,
    Literal(String),
    CandidateEnd(&'input str),
    CandidateInterpolation(&'input str),
    QuotesCandidateInterpolation(&'input str),
    End,
    Interpolation,
}

The tokens in multiline string mode.

Variants

Error

Literal(String)

CandidateEnd(&'input str)

A candidate end. A multiline string starting delimiter MultiStringStart can have a variable number of % character, so the lexer matches candidate end delimiter, compare the number of characters, and either emit the End token above, or turn the CandidateEnd to a FalseEnd otherwise

CandidateInterpolation(&'input str)

Same as CandidateEnd, but for interpolation

QuotesCandidateInterpolation(&'input str)

Unfortunate consequence of Logos’ issue#200. The other rules should be sufficient to match this as a double quote followed by a CandidateInterpolation, but if we omit this token, the lexer can fail unexpectedly on valid inputs because of #200.

End

Token emitted by the modal lexer for the parser once it has decided that a CandidateEnd is an actual end token.

Trait Implementations

impl<'input> Clone for MultiStringToken<'input>

fn clone(&self) -> MultiStringToken<'input>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'input> Debug for MultiStringToken<'input>

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

Formats the value using the given formatter.

impl<'s> Logos<'s> for MultiStringToken<'s>

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<'input> PartialEq for MultiStringToken<'input>

fn eq(&self, other: &MultiStringToken<'input>) -> bool

Tests for self and other values to be equal, and is used by ==.

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

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