Trait Parse

pub trait Parse {
    // Required method
    fn parse(lexer: &mut LexerBridge<'_>) -> ParseResult<Self>
       where Self: Sized;

    // Provided methods
    fn parse_sep(
        lexer: &mut LexerBridge<'_>,
        join: Tokens,
    ) -> ParseResult<Vec<Self>>
       where Self: Sized { ... }
    fn parse_sep_end(
        lexer: &mut LexerBridge<'_>,
        join: Tokens,
        end: Tokens,
    ) -> ParseResult<Vec<Self>>
       where Self: Sized { ... }
}

The main trait for parsing.

Any node that can be parsed must implement this trait.

Required Methods

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

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.

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.
