Enum ExistentialPredicate 

pub enum ExistentialPredicate {
    Trait(ExistentialTraitRef),
    Projection(ExistentialProjection),
    AutoTrait(DefId),
}

A predicate without Self, for use in dyn Trait.

Reflects [ty::ExistentialPredicate]

Variants

Trait(ExistentialTraitRef)

E.g. From<u64>. Note that this isn’t T: From<u64> with a given T, this is just From<u64>. Could be written ?: From<u64>.

Projection(ExistentialProjection)

E.g. Iterator::Item = u64. Could be written <? as Iterator>::Item = u64.

AutoTrait(DefId)

E.g. Send.

Trait Implementations

impl Clone for ExistentialPredicate

fn clone(&self) -> ExistentialPredicate

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ExistentialPredicate

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

Formats the value using the given formatter.

impl Hash for ExistentialPredicate

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 ExistentialPredicate

fn eq(&self, other: &ExistentialPredicate) -> 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.
