Enum DropData

pub enum DropData {
    Noop,
    Implicit,
    Glue {
        ty: Ty,
        impl_exprs: Vec<ImplExpr>,
    },
}

Variants

Noop

A drop that does nothing, e.g. for scalars and pointers.

Implicit

An implicit Drop local clause, if the resolve_drop_bounds option is false. If that option is true, we’ll add Drop bounds to every type param, and use that to resolve Drop impls of generics. If it’s false, we use this variant to indicate that the drop clause comes from a generic or associated type.

Glue

The implicit Drop impl that exists for every type without an explicit Drop impl. The virtual impl is considered to have one T: Drop bound for each generic argument of the target type; it then simply drops each field in order.

Fields

ty: Ty

The type we’re generating glue for.

impl_exprs: Vec<ImplExpr>

The ImplExprs for the T: Drop bounds of the virtual impl. There is one for each generic argument, in order.

Trait Implementations

impl Clone for DropData

fn clone(&self) -> DropData

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DropData

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for DropData

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for DropData

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 DropData

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.

fn is_referenceable() -> bool

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

impl Ord for DropData

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

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

fn partial_cmp(&self, other: &DropData) -> 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: UnderOwnerState<'tcx>> SInto<S, DropData> for DropData<'tcx>

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

impl Serialize for DropData

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for DropData
