# Struct syn::QSelf

source · [−]

    pub struct QSelf {
        pub lt_token: Lt,
        pub ty: Box<Type>,
        pub position: usize,
        pub as_token: Option<As>,
        pub gt_token: Gt,
    }

Expand description

The explicit Self type in a qualified path: the `T` in `<T as Display>::fmt`.

The actual path, including the trait and the associated item, is stored separately. The `position` field 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

This type is available only if Syn is built with the `"derive"` or `"full"` feature.

## Fields

`lt_token: Lt` `ty: Box<Type>` `position: usize` `as_token: Option<As>` `gt_token: Gt`
