This "bubble up an error" macro was originally named if_ok! in order to get it
landed, but after the fact it was discovered that this name is not exactly
desirable.
The name
if_ok!
isn't immediately clear that is has much to do with errorhandling, and it doesn't look fantastic in all contexts (if if_ok!(...) {}). In
general, the agreed opinion about
if_ok!
is that is came in as subpar.The name
try!
is more invocative of error handling, it's shorter by 2 letters,and it looks fitting in almost all circumstances. One concern about the word
try!
is that it's too invocative of exceptions, but the belief is that thiswill be overcome with documentation and examples.
