Description
The is_success
and is_failure
functions/methods in core::result should be called is_ok
and is_err
instead, so that they correlate with the enum's tag names. These functions were originally called success
/ failure
presumably to avoid clashing with the enum's tags (i.e. the functions could not be called ok
/ err
), but now that they are prefixed with is_
then these additional names are not required.
An independent issue is that the documentation for is_failure
(perhaps becoming is_err
) should say "Returns true if the result is err
" rather than "Returns true if the result is error
" - because the enum tag is called err
not error
.
