Modules

debug

Macros

err

Creates error Result from message, file and location

log

Prints with newline to stdout in debug profile

logn

Prints without newline to stdout in debug profile

rustemo_mod

Loads generated parser modules from the Cargo OUT_DIR location.

Structs

Forest

Shared Packed Parse Forest (SPPF) returned by the GLR parser.

GlrParser

An implementation of Right-Nulled GLR parsing (RNGLR)

GssHead

A node/head in the Graph Structured Stack (GSS). Implements Context for GLR parsing.

LRContext

Context implementation for LR parsing

LRParser

An implementation of LR parsing

LineColumn

A line-column based location for use where applicable (e.g. plain text).

Location

Describes a span from start till end in the parsed input.

SliceBuilder

Returns a slice of the matched input. If no match is possible None is returned.

StringLexer

A lexer that operates over string inputs and uses generated string and regex recognizers provided by the parser table.

Token

Represents a single token from the input stream.

TreeBuilder

TreeBuilder is a builder that builds a generic concrete parse tree.

ValLoc

Value with location. Used in place of parsed values which need locations to report errors during semantic analysis.

Enums

Action

An action executed by the (G)LR Parser during parsing

Error

Error type returned in Err variant of Result type from the parser.

Position

A position in the input file.

TreeNode

A node in the generic tree produced by TreeBuilder

Traits

Builder

Builds output during parsing by using semantic actions.

Context

Lexer/Parser context is used to keep the state. It provides necessary information to parsers and actions.

Input

Input is a sliceable sequence-like type with a concept of length.

LRBuilder

A builder variant for LR parsing.

Lexer

The trait implemented by all Rustemo lexers

Parser

The trait implemented by all Rustemo parsers.

ParserDefinition

Provides LR actions and GOTOs given the state and term/nonterm.

State

This trait must be implemented by the parser state type.

TokenRecognizer

The trait implemented by types used to recognize tokens in string inputs. Used by StringLexer.
