Summary
This PR adds additional
#[fail(name = ...)]
attribute intofailure_derive
, which allows to specify custom error's name instead of automatically generated. If no attribute is specified then current behavior is preserved.Motivation
It appears to be handy to use
Fail::name()
for custom error codes in the code base of the same application. However, doing so disallows derive usage as we need to implementFail
manually. Having ability to overrideFail::name()
result in derive simplifies things a lot.Checklist
