Enum CoreDef

pub enum CoreDef {
    Export(CoreExport<EntityIndex>),
    InstanceFlags(RuntimeComponentInstanceIndex),
    Trampoline(TrampolineIndex),
}

Definition of a core wasm item and where it can come from within a component.

Note that this is sort of a result of data-flow-like analysis on a component during compile time of the component itself. References to core wasm items are “compiled” to either referring to a previous instance or to some sort of lowered host import.

Variants

Export(CoreExport<EntityIndex>)

This item refers to an export of a previously instantiated core wasm instance.

InstanceFlags(RuntimeComponentInstanceIndex)

This is a reference to a wasm global which represents the runtime-managed flags for a wasm instance.

Trampoline(TrampolineIndex)

This is a reference to a Cranelift-generated trampoline which is described in the trampolines array.

Trait Implementations

impl Clone for CoreDef

fn clone(&self) -> CoreDef

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for CoreDef

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for CoreDef

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<T> From<CoreExport<T>> for CoreDef

where EntityIndex: From<T>,

fn from(export: CoreExport<T>) -> CoreDef

Converts to this type from the input type.

impl Hash for CoreDef

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 CoreDef

fn eq(&self, other: &CoreDef) -> 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 Serialize for CoreDef

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 CoreDef

impl StructuralPartialEq for CoreDef
