Module pratt_parser 

Constructs useful in prefix, postfix, and infix operator parsing with the Pratt parsing method.

Macros

pratt_precedence

Convenience macro for building a const Pratt parser precedence table.

Structs

ConstPrattParser

A Pratt parser that can be built in a const context and stored in static memory.

Op

An operator that corresponds to a rule.

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*)*

PrattParserMap

Product of calling map_primary on a PrattParser or ConstPrattParser, defines how expressions should be mapped.

Enums

Assoc

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

Type Aliases

Prec

Operator precedence level.
