Enum fibers::sync::oneshot::MonitorError

pub enum MonitorError<E> {
    Aborted,
    Failed(E),
}

The reason that a monitored peer has not completed successfully.

Variants

Aborted

The monitor channel is disconnected.

Failed(E)

The monitored peer has exited with an error E.

i.e., Monitored::exit(self, Err(E)) was called

Methods

impl<E> MonitorError<E>

pub fn map<F, T>(self, f: F) -> MonitorError<T> where
    F: FnOnce(E) -> T, 

Maps an MonitorError<E> to MonitorError<T> by applying a function to a contained error.

Examples

use fibers::sync::oneshot::MonitorError;

let mut e = MonitorError::Failed(10);
assert_eq!(e.map(|v| v.to_string()), MonitorError::Failed("10".to_string()));

e = MonitorError::Aborted;
assert_eq!(e.map(|v| v.to_string()), MonitorError::Aborted);

pub fn unwrap_or(self, or_error: E) -> E

Unwraps MonitorError and returns the internal error E.

If self is MonitorError::Aborted, or_error will be returned.

Examples

use fibers::sync::oneshot::MonitorError;

let e = MonitorError::Aborted;
assert_eq!(e.unwrap_or(10), 10);

let e = MonitorError::Failed(20);
assert_eq!(e.unwrap_or(10), 20);

pub fn unwrap_or_else<F>(self, f: F) -> E where
    F: FnOnce() -> E, 

Unwraps MonitorError and returns the internal error E.

If self is MonitorError::Aborted, the result of f() will be returned.
