Detailed Description

template<typename T>
class llvm::FailureOr< T >

This class provides support for representing a failure result, or a valid value of type T.

This allows for integrating with LogicalResult, while also providing a value on the success path.

FailureOr() [1/5]

template<typename T>

llvm::FailureOr< T >::FailureOr ( LogicalResult Result )

inline

Allow constructing from a LogicalResult.

The result must be a failure. Success results should use a proper instance of type T.
