Crate flexi_parse

flexi-parse is a crate for parsing arbitrary syntax into a syntax tree. It is intended to be more flexible than a parser generator or parser combinator, while still being simple to use.

Modules

• error
  Types for error reporting.
• group
  Streams of tokens delimited by punctuation.
• punctuated
  Utilities for parsing types separated by punctuation.
• token
  Tokens representing punctuation, identifiers, keywords, and whitespace.

Macros

• Punct
  A macro to get the type of a punctuation token.
• group
  A macro to easily parse a delimited group.
• keywords
  Generate types for keywords.
• keywords_prefixed
  Generate types for keywords, with the type names prefixed with keyword_.
• peek2_any
  Returns true if ParseBuffer::peek2 would return true for any types passed.
• peek_any
  Returns true if ParseBuffer::peek would return true for any types passed.

Structs

• Lookahead
  A type for peeking at the next token, and generating a helpful error if it isn’t an expected type.
• ParseBuffer
  A cursor position within a token stream.
• SourceFile
  A struct representing a file of source code.
• Span
  A region of source code.
• TokenStream
  A sequence of tokens.

Traits

• Parse
  Parsing interface for types with a default parsing method.
• Parser
  A parser that can parse a stream of tokens into a syntax tree node.
• Peek
  Types that can be parsed by looking at a single token.

Functions

• new_error
  Creates a new error in the given source file, at the given location, and with the given message and code.
• parse
  Parses the given tokens into the syntax tree node T.
• parse_repeated
  Attempts to repeatedly parse input into the given syntax tree node, using T’s default parsing implementation, and continuing until input is exhausted.
• parse_source
  Scans and parses the given source file into the syntax tree node T.
• parse_string
  Scans and parses the given string into the syntax tree node T.
• pretty_unwrapariadne
  Gets the Ok value, panicking with a formatted error message if the value is Err.

Type Aliases

• ParseStream
  The input type for all parsing functions. This is a stable alias for ParseBuffer.
• Result
  The return type of a parsing function.
