Struct rustc_ast::tokenstream::AttrAnnotatedTokenStream

source · [−]

pub struct AttrAnnotatedTokenStream(pub Lrc<Vec<(AttrAnnotatedTokenTree, Spacing)>>);

Expand description

A AttrAnnotatedTokenStream is similar to a TokenStream, but with extra information about the tokens for attribute targets. This is used during expansion to perform early cfg-expansion, and to process attributes during proc-macro invocations.

Implementations

source

impl AttrAnnotatedTokenStream

source

pub fn new(
tokens: Vec<(AttrAnnotatedTokenTree, Spacing)>
) -> AttrAnnotatedTokenStream

source

pub fn to_tokenstream(&self) -> TokenStream

Converts this AttrAnnotatedTokenStream to a plain TokenStream During conversion, AttrAnnotatedTokenTree::Attributesget 'flattened' back to aTokenStreamof the formouter_attr attr_target`. If there are inner attributes, they are inserted into the proper place in the attribute target tokens.
