TENSORSTORE_RETURN_IF_ERROR(...);
Causes the containing function to return the specified
absl::Status
value if it is an error status.Example:
absl::Status GetSomeStatus(); absl::Status Bar() { TENSORSTORE_RETURN_IF_ERROR(GetSomeStatus()); // More code return absl::OkStatus(); }
An optional second argument specifies the return expression in the case of an error. A variable
_
is bound to the value of the first expression is in scope within this expression. For example:TENSORSTORE_RETURN_IF_ERROR(GetSomeStatus(), MaybeAnnotateStatus(_, "In Bar")); TENSORSTORE_RETURN_IF_ERROR(GetSomeStatus(), MakeReadyFuture(_));
Warning
The
absl::Status
expression must not contain any commas outside parentheses (such as in a template argument list); if necessary, to ensure this, it may be wrapped in additional parentheses as needed.
