Structs

Op

An operator that corresponds to a rule.

Pair

A matching pair of Tokens and everything between them.

Pairs

An iterator over Pairs. It is created by pest::state and Pair::into_inner.

PaxParser

Pest parser generated from the Pax grammar.

PrattParser

Struct containing operators and precedences, which can perform Pratt parsing on primary, prefix, postfix and infix expressions over Pairs. The tokens in Pairs should alternate in the order: prefix* ~ primary ~ postfix* ~ (infix ~ prefix* ~ primary ~ postfix*)*

Span

A span over a &str. It is created from either two Positions or from a Pair.

Enums

Assoc

Associativity of an infix binary operator, used by Op::infix(Assoc).

Rule

Traits

Computable

Trait for expression types that can be computed to a value

Parser

A trait with a single method that parses strings.

Functions

get_pax_pratt_parser

Build the Pratt parser that encodes PAXEL operator precedence and associativity.

parse_pax_err

Parse a string against a Pax grammar rule, preserving the structured pest error.

parse_pax_pairs

Parse a string into pest pairs for a Pax grammar rule.

parse_pax_str

Parse a string against a single Pax grammar rule, returning a human-readable error string.

Derive Macros

Parser

The main method that’s called by the proc macro (a wrapper around pest_generator::derive_parser)
