Struct wasm_bindgen::convert::WasmRet
source · #[repr(C)]pub struct WasmRet<T: WasmAbi> { /* private fields */ }
Expand description
A repr(C) struct containing all of the primitives of a WasmAbi
type, in
order.
This is used as the return type of imported/exported functions. WasmAbi
types aren’t guaranteed to be FFI-safe, so we can’t return them directly:
instead we return this.
If all but one of the primitives is ()
, this corresponds to returning the
remaining primitive directly, otherwise a return pointer is used.
