Struct wasmer_vm::VMExportFunction

pub struct VMExportFunction {
    pub address: *const VMFunctionBody,
    pub vmctx: VMFunctionEnvironment,
    pub signature: FunctionType,
    pub kind: VMFunctionKind,
    pub call_trampoline: Option<VMTrampoline>,
    pub instance_ref: Option<InstanceRef>,
}

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<InstanceRef>

A “reference” to the instance through the InstanceRef. None if it is a host function.

Trait Implementations

impl Clone for VMExportFunction

pub fn clone(&self) -> VMExportFunction

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for VMExportFunction

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

Formats the value using the given formatter.

impl From<VMExportFunction> for VMExport

pub fn from(func: VMExportFunction) -> Self

Performs the conversion.

impl PartialEq<VMExportFunction> for VMExportFunction

pub fn eq(&self, other: &VMExportFunction) -> bool

This method tests for self and other values to be equal, and is used by ==.

pub fn ne(&self, other: &VMExportFunction) -> bool

This method tests for !=.

impl Send for VMExportFunction

Safety

There is no non-threadsafe logic directly in this type. Calling the function may not be threadsafe.

impl StructuralPartialEq for VMExportFunction

impl Sync for VMExportFunction

Safety

The members of an VMExportFunction are immutable after construction.
