Crate rustemo

This crate is the runtime for the generated Rustemo parsers.

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.
