Modules

• token_stream
  Public implementation details for the TokenStream type, such as iterators.
• tracked_envExperimental
  Tracked access to environment variables.
• tracked_pathExperimental
  Tracked access to additional files.

Macros

• quoteExperimental
  quote!(..) accepts arbitrary tokens and expands into a TokenStream describing the input. For example, quote!(a + b) will produce an expression, that, when evaluated, constructs the TokenStream [Ident("a"), Punct('+', Alone), Ident("b")].

Structs

• Group
  A delimited token stream.
• Ident
  An identifier (ident).
• LexError
  Error returned from TokenStream::from_str.
• Literal
  A literal string ("hello"), byte string (b"hello"), character ('a'), byte character (b'a'), an integer or floating point number with or without a suffix (1, 1u8, 2.3, 2.3f32). Boolean literals like true and false do not belong here, they are Idents.
• Punct
  A Punct is a single punctuation character such as +, - or #.
• Span
  A region of source code, along with macro expansion information.
• TokenStream
  The main type provided by this crate, representing an abstract stream of tokens, or, more specifically, a sequence of token trees. The type provides interfaces for iterating over those token trees and, conversely, collecting a number of token trees into one stream.
• DiagnosticExperimental
  A structure representing a diagnostic message and associated children messages.
• ExpandErrorExperimental
  Error returned from TokenStream::expand_expr.
• SourceFileExperimental
  The source file of a given Span.

Enums

• Delimiter
  Describes how a sequence of token trees is delimited.
• Spacing
  Indicates whether a Punct token can join with the following token to form a multi-character operator.
• TokenTree
  A single token or a delimited sequence of token trees (e.g., [1, (), ..]).
• LevelExperimental
  An enum representing a diagnostic level.

Traits

• MultiSpanExperimental
  Trait implemented by types that can be converted into a set of Spans.

Functions

• is_available
  Determines whether proc_macro has been made accessible to the currently running program.
• quoteExperimental
  Quote a TokenStream into a TokenStream. This is the actual implementation of the quote!() proc macro.
• quote_spanExperimental
  Quote a Span into a TokenStream. This is needed to implement a custom quoter.
