impl LongRefFromWasmAbi for SiImage

type Abi = u32

Same as RefFromWasmAbi::Abi

type Anchor = Ref<'static, SiImage>

Same as RefFromWasmAbi::Anchor

unsafe fn long_ref_from_abi(js: Self::Abi) -> Self::Anchor

Same as RefFromWasmAbi::ref_from_abi

impl OptionFromWasmAbi for SiImage

fn is_none(abi: &Self::Abi) -> bool

Tests whether the argument is a “none” instance. If so it will be deserialized as None, and otherwise it will be passed to FromWasmAbi.

impl OptionIntoWasmAbi for SiImage

fn none() -> Self::Abi

impl RefFromWasmAbi for SiImage

type Abi = u32

The wasm ABI type references to Self are recovered from.

type Anchor = Ref<'static, SiImage>

The type that holds the reference to Self for the duration of the invocation of the function that has an &Self parameter. This is required to ensure that the lifetimes don’t persist beyond one function call, and so that they remain anonymous.
