Structs

• CaptureState 🔒
• ClosureSpans 🔒
  Stores span information about a closure.
• NodeRange 🔒
  A token range within an individual AST node’s (lazy) token stream, i.e. relative to that node’s first token. Distinct from ParserRange so the two kinds of range can’t be mixed up.
• Parser
• ParserRange 🔒
  A token range within a Parser’s full token stream.
• Restrictions 🔒
• SeqSep 🔒
  A sequence separator.
• TokenCursor 🔒
  Iterator over a TokenStream that produces Tokens. It’s a bit odd that we (a) lex tokens into a nice tree structure (TokenStream), and then (b) use this type to emit them as a linear sequence. But a linear sequence is what the parser expects, for the most part.

Enums

• AttemptLocalParseRecovery
• BlockMode 🔒
• Capturing 🔒
  Controls how we capture tokens. Capturing can be expensive, so we try to avoid performing capturing in cases where we will never need an AttrTokenStream.
• CommaRecoveryMode
  Whether or not to recover a a, b when parsing patterns as (a, b) or that and a | b.
• FlatToken 🔒
  A helper struct used when building an AttrTokenStream from a LazyAttrTokenStream. Both delimiter and non-delimited tokens are stored as FlatToken::Token. A vector of FlatTokens is then ‘parsed’ to build up an AttrTokenStream with nested AttrTokenTree::Delimited tokens.
• FollowedByType
• ForceCollect
  Whether or not we should force collection of tokens for an AST node, regardless of whether or not it has attributes
• ParseNtResult
• RecoverColon
  Whether or not to recover a : when parsing patterns that were meant to be paths.
• RecoverComma
  Whether or not to recover a , when parsing or-patterns.
• Recovery
• SemiColonMode 🔒
• TokenDescription 🔒
• TokenType 🔒
• Trailing 🔒

Type Aliases

• NodeReplacement 🔒
  See the comment on ParserReplacement.
• ParserReplacement 🔒
  Indicates a range of tokens that should be replaced by an AttrsTarget (replacement) or be replaced by nothing (deletion). This is used in two places during token collection.
