Struct ItemRef

pub struct ItemRef {
    pub(crate) contents: Node<ItemRefContents>,
}

Reference to an item, with generics. Basically any mention of an item (function, type, etc) uses this.

This can refer to a top-level item or to a trait associated item. Example:

trait MyTrait<TraitType, const TraitConst: usize> {
  fn meth<MethType>(...) {...}
}
fn example_call<TraitType, SelfType: MyTrait<TraitType, 12>>(x: SelfType) {
  x.meth::<String>(...)
}

Here, in the call x.meth::<String>(...) we will build an ItemRef that looks like:

ItemRef {
    def_id = MyTrait::meth,
    generic_args = [String],
    impl_exprs = [<proof of `String: Sized`>],
    in_trait = Some(<proof of `SelfType: MyTrait<TraitType, 12>`>,
}

The in_trait ImplExpr will have in its trait field a representation of the SelfType: MyTrait<TraitType, 12> predicate, which looks like:

ItemRef {
    def_id = MyTrait,
    generic_args = [SelfType, TraitType, 12],
    impl_exprs = [],
    in_trait = None,
}

Fields

contents: Node<ItemRefContents>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ItemRef

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ItemRef

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for ItemRef

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 ItemRef

fn is_referenceable() -> bool

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

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(generator: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

impl Ord for ItemRef

fn cmp(&self, other: &ItemRef) -> 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 ItemRef

fn eq(&self, other: &ItemRef) -> 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 ItemRef

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

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

fn lt(&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 Deref for ItemRef

type Target = ItemRefContents

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.
