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

pub 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

The type of error that this future will resolve with if it fails in a normal fashion.

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,

Fuse a future such that poll and cancel will never again be called once it has completed.

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

Converts the resulting future into a boxed trait object.
