[−][src]Trait casco::stream::TokenStream

pub trait TokenStream: IntoIterator<Item = TokenTree<Self>> {
    type Group: Group<Self> + Spanned<Self::Span> + Clone + Debug;
    type Ident: Ident + Spanned<Self::Span> + Clone + Debug;
    type Literal: Literal + Spanned<Self::Span> + Clone + Debug;
    type Punct: Punct + Spanned<Self::Span> + Clone + Debug;
    type Span: Copy + Debug;
}

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.

Associated Types

`type Group: Group<Self> + Spanned<Self::Span> + Clone + Debug`

A delimited token stream.

`type Ident: Ident + Spanned<Self::Span> + Clone + Debug`

An identifier.

`type Literal: Literal + Spanned<Self::Span> + Clone + Debug`

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.
