Expand description

General-purpose expression tokenizer and predicate parser.

The public API has two layers:

Tokens — Token enum + tokenize() produce a flat token stream from any expression string. Consumers build their own grammar on top (selectors, queries, filters, etc.).
Predicates — Predicate struct + parse_predicate() parse bracket-content expressions (name op? value?).

Structs§

Predicate: A predicate expression: name, name=value, name^=value, etc.
Tokenizer: Configurable tokenizer with custom operators, keywords, and middleware.

eval_op: Evaluate a predicate operator against two string values.
eval_op_typed: Evaluate a predicate operator with typed values.
eval_predicate: Evaluate a predicate operator string against a node value and a predicate value.
parse_predicate: Parse a single predicate expression from bracket content.
parse_predicate_list: Parse a comma-separated list of predicates from bracket content.
tokenize: Tokenize an input string with default (built-in) operators and keywords.
