Trait Implementations§

Source§

impl<'db> Parse<'db> for KeywordPerm

Source§

type Output = AstPerm<'db>

Source§

fn opt_parse( db: &'db dyn Db, tokens: &mut Parser<'_, 'db>, ) -> Result<Option<AstPerm<'db>>, ParseFail<'db>>

Parse a single instance of Self, returning Ok(Some(v)). Returns Ok(None) if Self was not present or Err(err) if Self appeared to be present but was ill-formed. Read more
Source§

fn expected() -> Expected

Source§

fn can_eat(db: &'db dyn Db, parser: &Parser<'_, 'db>) -> bool

Speculatively parses to see if we could eat a Self without any error. Never consumes tokens nor produces an error.
Source§

fn eat( db: &'db dyn Db, parser: &mut Parser<'_, 'db>, ) -> Result<Self::Output, ParseFail<'db>>

Parses an instance of Self from the given Parser, reporting an error if no instance is found.
Source§

fn eat_comma( db: &'db dyn Db, parser: &mut Parser<'_, 'db>, ) -> Result<SpanVec<'db, Self::Output>, ParseFail<'db>>

Parse zero-or-more comma-separated instances of Self returning a vector. Accepts trailing commas.
Source§

fn eat_many( db: &'db dyn Db, parser: &mut Parser<'_, 'db>, ) -> Result<SpanVec<'db, Self::Output>, ParseFail<'db>>

Parse zero-or-more instances of Self returning a vector.
Source§

fn eat_delimited<T>( db: &'db dyn Db, parser: &mut Parser<'_, 'db>, delimiter: Delimiter, eat_method: impl FnOnce(&'db dyn Db, &mut Parser<'_, 'db>) -> Result<T, ParseFail<'db>>, ) -> Result<T, ParseFail<'db>>

Eat a comma separated list of Self, delimited by delimiter (e.g., (a, b, c)).
Source§

fn opt_parse_delimited<T>( db: &'db dyn Db, parser: &mut Parser<'_, 'db>, delimiter: Delimiter, eat_method: impl FnOnce(&'db dyn Db, &mut Parser<'_, 'db>) -> Result<T, ParseFail<'db>>, ) -> Result<Option<T>, ParseFail<'db>>

Parse a delimited list of Self e.g., (a, b, c) or [a, b, c]. Returns None if the given delimiters indicated by delimiter are not found.
Source§

fn opt_parse_comma( db: &'db dyn Db, parser: &mut Parser<'_, 'db>, ) -> Result<Option<SpanVec<'db, Self::Output>>, ParseFail<'db>>

Parse a comma separated list of Self
Source§

fn opt_parse_separated( db: &'db dyn Db, parser: &mut Parser<'_, 'db>, separator: Op, ) -> Result<Option<SpanVec<'db, Self::Output>>, ParseFail<'db>>

Parse a separator separated list of Self
Source§

fn opt_parse_guarded( guard_op: impl ParseGuard, db: &'db dyn Db, parser: &mut Parser<'_, 'db>, ) -> Result<Option<Self::Output>, ParseFail<'db>>

If guard_op appears, then parse Self
