Enum haybale::ReturnValue

pub enum ReturnValue<V> {
    Return(V),
    ReturnVoid,
    Throw(V),
    Abort,
}

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)

Trait Implementations

impl<V: Clone> Clone for ReturnValue<V>

fn clone(&self) -> ReturnValue<V>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<V: Debug> Debug for ReturnValue<V>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<V: Hash> Hash for ReturnValue<V>

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<V: PartialEq> PartialEq for ReturnValue<V>

fn eq(&self, other: &ReturnValue<V>) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
