Expand description
This crate is the runtime for the generated Rustemo parsers.
Modules§
Macros§
- Creates error Result from message, file and location
- Prints with newline to stdout in debug profile
- Prints without newline to stdout in debug profile
- Loads generated parser modules from the Cargo OUT_DIR location.
Structs§
- Shared Packed Parse Forest (SPPF) returned by the GLR parser.
- An implementation of Right-Nulled GLR parsing (RNGLR)
- A node/head in the Graph Structured Stack (GSS). Implements
Context
for GLR parsing. Context
implementation for LR parsing- An implementation of LR parsing
- A line-column based location for use where applicable (e.g. plain text).
- Describes a span from start till end in the parsed input.
- Returns a slice of the matched input. If no match is possible
None
is returned. - A lexer that operates over string inputs and uses generated string and regex recognizers provided by the parser table.
- Represents a single token from the input stream.
- TreeBuilder is a builder that builds a generic concrete parse tree.
- Value with location. Used in place of parsed values which need locations to report errors during semantic analysis.
Enums§
- An action executed by the (G)LR Parser during parsing
- Error type returned in
Err
variant ofResult
type from the parser. - A position in the input file.
- A node in the generic tree produced by
TreeBuilder
Traits§
- Builds output during parsing by using semantic actions.
- Lexer/Parser context is used to keep the state. It provides necessary information to parsers and actions.
- Input is a sliceable sequence-like type with a concept of length.
- A builder variant for LR parsing.
- The trait implemented by all Rustemo lexers
- The trait implemented by all Rustemo parsers.
- Provides LR actions and GOTOs given the state and term/nonterm.
- This trait must be implemented by the parser state type.
- The trait implemented by types used to recognize tokens in string inputs. Used by
StringLexer
