Struct rustc_ap_rustc_ast::ast::QSelf

pub struct QSelf {
    pub ty: P<Ty>,
    pub path_span: Span,
    pub position: usize,
}

The explicit Self type in a "qualified path". The actual path, including the trait and the associated item, is stored separately. position represents the index of the associated item qualified with this Self type.

<Vec<T> as a::b::Trait>::AssociatedItem
 ^~~~~     ~~~~~~~~~~~~~~^
 ty        position = 3

<Vec<T>>::AssociatedItem
 ^~~~~    ^
 ty       position = 0

Fields

ty: P<Ty>

path_span: Span

The span of a::b::Trait in a path like <Vec<T> as a::b::Trait>::AssociatedItem; in the case where position == 0, this is an empty span.

position: usize
