Module casco::stream

Types and traits that provide an abstraction over proc_macro2.

Structs

MultiSpan

Wraps multiple spans into a single struct.

Enums

Delimiter	Describes how a sequence of token trees is delimited.
Spacing	Whether a Punct is followed immediately by another Punct or followed by another token or whitespace.
TokenTree	A single token or a delimited sequence of token trees (e.g. [1, (), ..]).

Traits

Group	A delimited token stream.
Ident	An identifier (ident).
IntoTokenStream	Trait that converts a type into a token stream.
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 like +, - or #.
Spanned	Trait that is implemented by everything that has a span (e.g. groups, idents, literals, puncts, token trees).
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 an interface for iterating over those token trees and, conversely, collecting a number of token trees into one stream.
