template<typename T, typename E>

E&& VE_ResultBase< T, E >::error ( )

inline

Moves the error out of result. Once this is called, the VE_ResultBase object is in an undefined state and MUST NOT be accessed again.

Definition at line 46 of file VE_Result.h.

template<typename T, typename E>

bool VE_ResultBase< T, E >::ok ( ) const

inline

Returns true if we have a valid result. Otherwise, we have an error.

Definition at line 33 of file VE_Result.h.

template<typename T, typename E>

T VE_ResultBase< T, E >::peek ( )

inline

Copies the value out for classes that suuport copying, allowing result to still be used. I am not sure if this is an actually a useful method to have, and am worried it might provide a false sense of safety around accessing result values multiply times.

template<typename T, typename E>

T&& VE_ResultBase< T, E >::unpack ( )

inline

Moves the value out of result. Once this is called, the VE_ResultBase object is in an undefined state and MUST NOT be accessed again.
