Struct elfo::MoveOwnership

pub struct MoveOwnership<T>(_);

Used to transfer ownership over messaging.

Messages must be instances of Clone, Serialize and Deserialize because of network communication and message dumping. However, in some cases, it’s desired to have messages that cannot satisfy requirements. For instance, when sending sockets or files.

MoveOwnership<T> implements Debug, Clone, Serialize and Deserialize for any T. Meanwhile, it can be serialized (but w/o useful information), it cannot be deserialized (it returns an error on attempts).

Example

#[message]
pub struct HandleFile {
    pub path: PathBuf,
    pub file: MoveOwnership<File>,
}

Implementations

impl<T> MoveOwnership<T>

pub fn take(&self) -> Option<T>

Takes the value. Next calls will return None.

Trait Implementations

impl<T> Clone for MoveOwnership<T>

pub fn clone(&self) -> MoveOwnership<T>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T> Debug for MoveOwnership<T>

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

Formats the value using the given formatter.

impl<'de, T> Deserialize<'de> for MoveOwnership<T>

pub fn deserialize<D>(
    _deserializer: D
) -> Result<MoveOwnership<T>, <D as Deserializer<'de>>::Error> where
    D: Deserializer<'de>, 

Deserialize this value from the given Serde deserializer.

impl<T> From<T> for MoveOwnership<T>

pub fn from(value: T) -> MoveOwnership<T>

Performs the conversion.

impl<T> Serialize for MoveOwnership<T>

pub fn serialize<S>(
    &self,
    serializer: S
) -> Result<<S as Serializer>::Ok, <S as Serializer>::Error> where
    S: Serializer, 

Serialize this value into the given Serde serializer.
