}Expand description
The main trait for parsing.
Any node that can be parsed must implement this trait.
Required Methods§
Sourcefn parse(lexer: &mut LexerBridge<'_>) -> ParseResult<Self>where
Self: Sized,
fn parse(lexer: &mut LexerBridge<'_>) -> ParseResult<Self>where
Self: Sized,
Given a lexer, try to parse a valid instance of this node.
§Errors
Should return a WagParseError if the parsing fails.
Provided Methods§
Sourcefn parse_sep(
lexer: &mut LexerBridge<'_>,
join: Tokens,
) -> ParseResult<Vec<Self>>where
Self: Sized,
fn parse_sep(
lexer: &mut LexerBridge<'_>,
join: Tokens,
) -> ParseResult<Vec<Self>>where
Self: Sized,
Parse multiple instances of this node, separated by a Tokens.
§Errors
Should return a WagParseError if the parsing fails.
Sourcefn parse_sep_end(
lexer: &mut LexerBridge<'_>,
join: Tokens,
end: Tokens,
) -> ParseResult<Vec<Self>>where
Self: Sized,
fn parse_sep_end(
lexer: &mut LexerBridge<'_>,
join: Tokens,
end: Tokens,
) -> ParseResult<Vec<Self>>where
Self: Sized,
Parse multiple instances of this node, separated by a Tokens end ended by a (possibly different) Tokens.
§Errors
Should return a WagParseError if the parsing fails.
Dyn Compatibility§
This trait is dyn compatible.
In older versions of Rust, dyn compatibility was called "object safety".
