Expand description

Macro which lets you wrap an existing error in a new error that implements the JsErrorClass trait. This macro however does currently not support the special identifiers that the JsError macro supports.

ยงExamples

js_error_wrapper!(std::net::AddrParseError, JsAddrParseError, "TypeError");
js_error_wrapper!(std::net::AddrParseError, JsAddrParseError, |err| {
  // match or do some logic to get the error class
  "TypeError"
});
