Todo:: couldn't that be replaced by a lib::Result<void> instance??

ExecResult ( )

inlineprotected

default: command executed successfully

Definition at line 72 of file handling-pattern.hpp.

◆ ExecResult() [2/2]

ExecResult ( lumiera::Error const & problem )

protected

this result marks a failed execution

Note: just grab and retain the error message, but clear the error flag. Rationale: by packaging into the ExecResult, the excepton counts as treated.
