Both Rust and Go can create an `UnmanagedVector`, which gives - * then ownership. Sometimes it is necessary to transfer ownership. - * - * ### Transfer ownership from Rust to Go - * - * When an `UnmanagedVector` was created in Rust using [`UnmanagedVector::new`], [`UnmanagedVector::default`] - * or [`new_unmanaged_vector`], it can be passed to Go as a return value (see e.g. [load_wasm][crate::load_wasm]). - * Rust then has no chance to destroy the vector anymore, so ownership is transferred to Go. - * In Go, the data has to be copied to a garbage collected `[]byte`. Then the vector must be destroyed - * using [`destroy_unmanaged_vector`]. - * - * ### Transfer ownership from Go to Rust - * - * When Rust code calls into Go (using the vtable methods), return data or error messages must be created - * in Go. This is done by calling [`new_unmanaged_vector`] from Go, which copies data into a newly created - * `UnmanagedVector`. Since Go created it, it owns it. The ownership is then passed to Rust via the - * mutable return value pointers. On the Rust side, the vector is destroyed using [`UnmanagedVector::consume`]. - * - * ## Examples - * - * Transferring ownership from Rust to Go using return values of FFI calls: - * - * ``` - * # use wasmvm::{cache_t, ByteSliceView, UnmanagedVector}; - * #[no_mangle] - * pub extern "C" fn save_wasm_to_cache( - * cache: *mut cache_t, - * wasm: ByteSliceView, - * error_msg: Option<&mut UnmanagedVector>, - * ) -> UnmanagedVector { - * # let checksum: Vec = Default::default(); - * // some operation producing a `let checksum: Vec` - * - * UnmanagedVector::new(Some(checksum)) // this unmanaged vector is owned by the caller - * } - * ``` - * - * Transferring ownership from Go to Rust using return value pointers: - * - * ```rust - * # use cosmwasm_vm::{BackendResult, GasInfo}; - * # use wasmvm::{Db, GoError, U8SliceView, UnmanagedVector}; - * fn db_read(db: &Db, key: &[u8]) -> BackendResult>> { - * - * // Create a None vector in order to reserve memory for the result - * let mut output = UnmanagedVector::default(); - * - * // … - * # let mut error_msg = UnmanagedVector::default(); - * # let mut used_gas = 0_u64; - * # let read_db = db.vtable.read_db.unwrap(); - * - * let go_error: GoError = read_db( - * db.state, - * db.gas_meter, - * &mut used_gas as *mut u64, - * U8SliceView::new(Some(key)), - * // Go will create a new UnmanagedVector and override this address - * &mut output as *mut UnmanagedVector, - * &mut error_msg as *mut UnmanagedVector, - * ) - * .into(); - * - * // We now own the new UnmanagedVector written to the pointer and must destroy it - * let value = output.consume(); - * - * // Some gas processing and error handling - * # let gas_info = GasInfo::free(); - * - * (Ok(value), gas_info) - * } - * ``` - * - * - * If you want to mutate data, you need to consume the vector and create a new one: - * - * ```rust - * # use wasmvm::{UnmanagedVector}; - * # let input = UnmanagedVector::new(Some(vec![0xAA])); - * let mut mutable: Vec = input.consume().unwrap_or_default(); - * assert_eq!(mutable, vec![0xAA]); - * - * // `input` is now gone and we cam do everything we want to `mutable`, - * // including operations that reallocate the underlying data. - * - * mutable.push(0xBB); - * mutable.push(0xCC); - * - * assert_eq!(mutable, vec![0xAA, 0xBB, 0xCC]); - * - * let output = UnmanagedVector::new(Some(mutable)); - * - * // `output` is ready to be passed around - * ``` - */ -typedef struct UnmanagedVector { - /** - * True if and only if this is None.
