A syntax feature that may or may not be supported depending on the file type and parser configuration

Required Associated Types

type Parser<'source>: Parser

Required Methods

fn is_supported(&self, p: &Self::Parser<'_>) -> bool

Returns true if the current parsing context supports this syntax feature.

Provided Methods

fn is_unsupported(&self, p: &Self::Parser<'_>) -> bool

Returns true if the current parsing context doesn’t support this syntax feature.

fn exclusive_syntax<'source, S, E, D>( &self, p: &mut Self::Parser<'source>, syntax: S, error_builder: E ) -> ParsedSyntax

where S: Into<ParsedSyntax>, E: FnOnce(&Self::Parser<'source>, &CompletedMarker) -> D, D: ToDiagnostic<Self::Parser<'source>>,

Adds a diagnostic and changes the kind of the node to SyntaxKind::to_bogus if this feature isn’t supported.

Returns the parsed syntax.

fn parse_exclusive_syntax<'source, P, E>( &self, p: &mut Self::Parser<'source>, parse: P, error_builder: E ) -> ParsedSyntax

where P: FnOnce(&mut Self::Parser<'source>) -> ParsedSyntax, E: FnOnce(&Self::Parser<'source>, &CompletedMarker) -> ParseDiagnostic,

Parses a syntax and adds a diagnostic and changes the kind of the node to SyntaxKind::to_bogus if this feature isn’t supported.

Returns the parsed syntax.

fn excluding_syntax<'source, S, E>( &self, p: &mut Self::Parser<'source>, syntax: S, error_builder: E ) -> ParsedSyntax

where S: Into<ParsedSyntax>, E: FnOnce(&Self::Parser<'source>, &CompletedMarker) -> ParseDiagnostic,

Adds a diagnostic and changes the kind of the node to SyntaxKind::to_bogus if this feature is supported.

Returns the parsed syntax.
