Struct elfo_core::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>
