Enum rustc_parse::parser::FlatToken

pub enum FlatToken {
    Token(Token),
    AttrTarget(AttributesData),
    Empty,
}

A helper struct used when building an AttrAnnotatedTokenStream from a LazyTokenStream. Both delimiter and non-delimited tokens are stored as FlatToken::Token. A vector of FlatTokens is then ‘parsed’ to build up an AttrAnnotatedTokenStream with nested AttrAnnotatedTokenTree::Delimited tokens

Variants

Token(Token)

Tuple Fields

0: Token

A token - this holds both delimiter (e.g. ‘{’ and ‘}’) and non-delimiter tokens

AttrTarget(AttributesData)

Tuple Fields

0: AttributesData

Holds the AttributesData for an AST node. The AttributesData is inserted directly into the constructed AttrAnnotatedTokenStream as an AttrAnnotatedTokenTree::Attributes

Empty

A special ‘empty’ token that is ignored during the conversion to an AttrAnnotatedTokenStream. This is used to simplify the handling of replace ranges.

Trait Implementations

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
