Represents success or an error with info about the error.
This class is typically used to indicate whether or not a function or other operation completed successfully. Success is indicated by an "OK" status. OK statuses will have .
code()
==
StatusCode::kOk
and .
ok()
== true
, with all other properties having empty values. All OK statuses are equal. Any non-OK Status
is considered an error. Users can inspect the error using the member functions, or they can simply stream the Status
object, and it will print itself in some human readable way (the streamed format may change over time and you should not depend on the specific format of a streamed Status
object remaining unchanged).
This is a regular value type that can be copied, moved, compared for equality, and streamed.
