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 🔒: A TokenStream cursor 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.
TokenTreeCursor 🔒

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 🔒
Trailing 🔒

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.
