Enum ExitStatus 

pub enum ExitStatus {
    Exited(i32),
    Signaled(Signal, bool),
    SignaledRaw(i32, bool),
}

Describes the result of a process after it has exited.

This is similar to std::process::ExitStatus, but is easier to match against and provides additional functionality like raise_or_exit that helps with propagating an exit status.

Variants

Exited(i32)

Program exited with an exit code.

Signaled(Signal, bool)

Program killed by signal, with or without a coredump.

SignaledRaw(i32, bool)

Program killed by a signal that nix’s [Signal] cannot name, a realtime signal (32 to 64), with or without a coredump. The number is the raw signal number (https://github.com/rrnewton/reverie/issues/997). It is only for numbers nix cannot name: build a status from a raw number with ExitStatus::signaled, which picks this or ExitStatus::Signaled.

Implementations

impl ExitStatus

pub const SUCCESS: ExitStatus

A successful exit status.

pub fn from_raw(code: i32) -> ExitStatus

Construct an ExitStatus from a raw exit code.

pub fn signaled(signal: i32, coredump: bool) -> ExitStatus

The status of a process killed by the raw signal signal: ExitStatus::Signaled when nix names it, else ExitStatus::SignaledRaw.

pub fn into_raw(self) -> i32

Converts the exit status into a raw number.

pub fn signal(&self) -> Option<i32>

If the process was terminated by a signal, returns that signal.

pub fn success(&self) -> bool

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

pub fn code(&self) -> Option<i32>

Returns the exit code of the process, if any. If the process was terminated by a signal, this will return None.

pub fn raise_or_exit(self) -> !

Propagate the exit status such that the current process exits in the same way that the child process exited.
