    fn return_abi(self) -> Self::Abi;
Expand description

A trait representing how to interepret the return value of a function for the wasm ABI.

This is very similar to the IntoWasmAbi trait and in fact has a blanket implementation for all implementors of the IntoWasmAbi. The primary use case of this trait is to enable functions to return Result, interpreting an error as “rethrow this to JS”

Required Associated Types§

Same as IntoWasmAbi::Abi

Required Methods§

Same as IntoWasmAbi::into_abi, except that it may throw and never return in the case of Err.
