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<'de> Deserialize<'de> for ProjectionPredicate

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

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 JsonSchema for ProjectionPredicate

fn schema_name() -> String

The name of the generated JSON Schema.

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

fn json_schema(gen: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn is_referenceable() -> bool

Whether JSON Schemas generated for this type should be re-used where possible using the $ref keyword.

impl Ord for ProjectionPredicate

fn cmp(&self, other: &ProjectionPredicate) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

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.

impl PartialOrd for ProjectionPredicate

fn partial_cmp(&self, other: &ProjectionPredicate) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl<'tcx, S: UnderBinderState<'tcx>> SInto<S, ProjectionPredicate> for ProjectionPredicate<'tcx>

fn sinto(&self, s: &S) -> ProjectionPredicate

impl Serialize for ProjectionPredicate

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
