Enum haybale::ReturnValue
source · pub enum ReturnValue<V> {
Return(V),
ReturnVoid,
Throw(V),
Abort,
}
Expand description
A simple enum describing the value returned from a function
Variants§
Return(V)
The function or call returns this value
ReturnVoid
The function or call returns void
Throw(V)
The function or call throws this value (using the LLVM invoke
/resume
mechanism, which is used for e.g. C++ exceptions)
(note that, unless other comments say otherwise, this is a pointer to the actual value or object thrown, not the value itself)
Abort
The function or call aborts without ever returning (e.g., with a Rust
panic, or by calling the C exit()
function)
