[−][src]Trait wasm_bindgen::convert::OptionFromWasmAbi
Indicates that this type can be received from JS as Option<Self>
.
This trait is used when implementing FromWasmAbi for Option<T>
.
Required methods
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
.
