Struct Parser 

pub struct Parser<'a> { /* private fields */ }

A parser for EventQL expressions and queries.

The parser takes a stream of tokens and builds an abstract syntax tree (AST) representing the structure of the EventQL query or expression.

Implementations

impl<'a> Parser<'a>

pub fn new(arena: &'a mut Arena, input: &'a [Token<'a>]) -> Self

Creates a new parser from a slice of tokens.

Example

use eventql_parser::Session;

let session = Session::builder().build();
let tokens = session.tokenize("1 + 2").unwrap();

pub fn parse_expr(&mut self) -> ParseResult<ExprRef>

Parses a single expression from the token stream.

This method can be used to parse individual expressions rather than complete queries. It’s useful for testing or for parsing expression fragments.

Returns

Returns the parsed expression, or a parse error if the tokens don’t form a valid expression.

Example

use eventql_parser::Session;

let session = Session::builder().build();
let tokens = session.tokenize("NOW()").unwrap();
