Expression tokenizer and predicate parser for AQL selectors

Role

• Parses predicate expressions inside attribute selectors (e.g. [method="POST"])
• Evaluates predicates against node attribute values
• Dependency of amql-selector

Features

• Predicate — parsed predicate (operator + value)
• PredicateOp — comparison operators (Eq, PrefixMatch, WordMatch, ...)
• PredicateValue — typed value (String, Number, Bool, Null)
• Token — tokenizer output

use aql_predicates::{parse_predicate, eval_predicate};

let pred = parse_predicate("POST")?;
assert!(eval_predicate("Eq", "POST", "POST"));
