- Use the predefined errors/functions or define a new one with the

macro to returns errors in functions that returnResult<T, Problem>
(an alias is provided in the library).- You can also use the extensions traits
ResultExt
,ProblemResultExt
,OptionExt
to handle common cases.

- Catch any desired error with
ProblemResultExt::catch_err
.
