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”
