Struct wasmer_vm::VMFunction [−][src]
pub struct VMFunction { pub address: *const VMFunctionBody, pub vmctx: VMFunctionEnvironment, pub signature: FunctionType, pub kind: VMFunctionKind, pub call_trampoline: Option<VMTrampoline>, pub instance_ref: Option<WeakOrStrongInstanceRef>, }
Expand description
A function export value.
Fields
address: *const VMFunctionBody
The address of the native-code function.
vmctx: VMFunctionEnvironment
Pointer to the containing VMContext
.
signature: FunctionType
The function type, used for compatibility checking.
kind: VMFunctionKind
The function kind (specifies the calling convention for the function).
call_trampoline: Option<VMTrampoline>
Address of the function call trampoline owned by the same VMContext that owns the VMFunctionBody.
May be None
when the function is a host function (FunctionType
== Dynamic
or vmctx
== nullptr
).
instance_ref: Option<WeakOrStrongInstanceRef>
A “reference” to the instance through the
InstanceRef
. None
if it is a host function.
Implementations
impl VMFunction
[src]
impl VMFunction
[src]pub fn upgrade_instance_ref(&mut self) -> Option<()>
[src]
pub fn upgrade_instance_ref(&mut self) -> Option<()>
[src]Converts the stored instance ref into a strong InstanceRef
if it is weak.
Returns None if it cannot be upgraded.

impl Send for VMFunction
[src]
Safety
There is no non-threadsafe logic directly in this type. Calling the function may not be threadsafe.
impl StructuralPartialEq for VMFunction
[src]
impl Sync for VMFunction
[src]
Safety
The members of an VMFunction are immutable after construction.
