Enum conch_runtime::ExitStatus

pub enum ExitStatus {
    Code(i32),
    Signal(i32),
}

Describes the result of a process after it has terminated.

Variants

Code(i32)

Normal termination with an exit code.

Signal(i32)

Termination by signal, with the signal number.

Never generated on Windows.

Methods

impl ExitStatus

fn success(&self) -> bool

Was termination successful? Signal termination not considered a success, and success is defined as a zero exit status.

impl<E: ?Sized> EnvFuture<E> for ExitStatus

type Item = Self

The type of value that this future will resolved with if it is successful.

type Error = Void

fn poll(&mut self, _env: &mut E) -> Poll<Self::Item, Self::Error>

Behaves identical to Future::poll when polled with a provided environment.

fn cancel(&mut self, _env: &mut E)

Cancel a future and consider it as completed, thus giving it a chance to run any clean up as if it had resolved on its own.

fn pin_env(self, env: E) -> Pinned<E, Self> where
    E: Sized,
    Self: Sized, 

Pin an environment to this future, allowing the resulting future to be polled from anywhere without needing the caller to specify an environment.

fn fuse(self) -> Fuse<Self> where
    Self: Sized,

fn boxed_result<'a>(self) -> BoxedResult<'a, Self> where
    Self: Sized,
    Self::Item: 'a + Future, 

Converts the resulting future into a boxed trait object.
