Module parser 

PromQL expression parser.

This module contains the parser for PromQL expressions. The main entry point is the expr() function which parses any valid PromQL expression.

Submodules

• aggregation - Aggregation grouping clauses (by, without)
• binary - Binary operators and modifiers
• expr - Main expression parser
• function - Built-in function definitions
• selector - Vector and matrix selectors
• subquery - Subquery expression parsing
• unary - Unary operators

Example

use rusty_promql_parser::parser::expr::expr;

let (rest, ast) = expr("sum(rate(http_requests[5m])) by (job)").unwrap();
assert!(rest.is_empty());

Re-exports

pub use expr::expr;
