Struct wasmtime_runtime::VMFunctionImport

#[repr(C)]
pub struct VMFunctionImport {
    pub wasm_call: NonNull<VMWasmCallFunction>,
    pub native_call: NonNull<VMNativeCallFunction>,
    pub array_call: VMArrayCallFunction,
    pub vmctx: *mut VMOpaqueContext,
}

An imported function.

Fields

wasm_call: NonNull<VMWasmCallFunction>

Function pointer to use when calling this imported function from Wasm.

native_call: NonNull<VMNativeCallFunction>

Function pointer to use when calling this imported function from native code.

array_call: VMArrayCallFunction

Function pointer to use when calling this imported function with the “array” calling convention that Func::new et al use.

vmctx: *mut VMOpaqueContext

The VM state associated with this function.

For Wasm functions defined by core wasm instances this will be *mut VMContext, but for lifted/lowered component model functions this will be a VMComponentContext, and for a host function it will be a VMHostFuncContext, etc.
