Struct ProjectionPredicate 

pub struct ProjectionPredicate {
    pub impl_expr: ImplExpr,
    pub assoc_item: AssocItem,
    pub ty: Ty,
}

Expresses a constraints over an associated type.

For instance:

fn f<T : Foo<S = String>>(...)
             ^^^^^^^^^^

(provided the trait Foo has an associated type S).

Fields

impl_expr: ImplExpr

The impl Trait for Ty in Ty: Trait<..., Type = U>.

assoc_item: AssocItem

The Type in Ty: Trait<..., Type = U>.

ty: Ty

The type U in Ty: Trait<..., Type = U>.

Trait Implementations

impl Clone for ProjectionPredicate

fn clone(&self) -> ProjectionPredicate

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ProjectionPredicate

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Hash for ProjectionPredicate

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for ProjectionPredicate

fn eq(&self, other: &ProjectionPredicate) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
