Expand description
Indicates that this type can be passed to JS as Option<Self>.
This trait is used when implementing IntoWasmAbi for Option<T>.
§⚠️ Unstable
This is part of the internal convert module, no
stability guarantees are provided. Use at your own risk. See its
documentation for more details.
Returns an ABI instance indicating “none”, which JS will interpret as
the None branch of this option.
It should be guaranteed that the IntoWasmAbi can never produce the ABI
value returned here.
This trait is not dyn compatible.
In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
