Enum workflow_wasm::convert::Cast

pub enum Cast<T>
where
    T: RefFromWasmAbi<Abi = u32> + LongRefFromWasmAbi<Abi = u32>,
{
    Ref(<T as RefFromWasmAbi>::Anchor),
    LongRef(<T as LongRefFromWasmAbi>::Anchor),
    Value(T),
}

A wrapper for a Rust object that can be either a reference or a value. This wrapper is used to carry a Rust (WASM ABI) reference provided by wasm_bindgen, but at the same time allows creation of a temporary object that can be created by interpreting the source user-supplied data. Cast then provides Cast::as_ref() to obtain the internally held reference and Cast::into_owned() where the latter will consume the value or clone the reference.

Variants

Ref(<T as RefFromWasmAbi>::Anchor)

LongRef(<T as LongRefFromWasmAbi>::Anchor)

Value(T)

Implementations

impl<T> Cast<T>

where T: RefFromWasmAbi<Abi = u32> + LongRefFromWasmAbi<Abi = u32> + Clone,

pub fn into_owned(self) -> T

Consume the Cast and return the owned value. If the Cast holds a reference, it will be cloned.

Trait Implementations

impl<T> AsRef<T> for Cast<T>

where T: RefFromWasmAbi<Abi = u32> + LongRefFromWasmAbi<Abi = u32>,

fn as_ref(&self) -> &T

Obtain a reference to the internally held value.

impl<T> Deref for Cast<T>

where T: RefFromWasmAbi<Abi = u32> + LongRefFromWasmAbi<Abi = u32> + Deref,

type Target = T

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl<T> From<T> for Cast<T>

where T: RefFromWasmAbi<Abi = u32> + LongRefFromWasmAbi<Abi = u32>,

Cast T value (struct) into Cast<T>

fn from(value: T) -> Cast<T>

Converts to this type from the input type.
