Struct rusty_fork::ExitStatusWrapper

pub struct ExitStatusWrapper(_);

Wraps std::process::ExitStatus. Historically, this was due to the wait_timeout crate having its own ExitStatus type.

Method documentation is copied from the Rust std docs and the wait_timeout docs.

Methods

impl ExitStatusWrapper

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.

On Unix, this will return None if the process was terminated by a signal; std::os::unix provides an extension trait for extracting the signal and other details from the ExitStatus.

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

Returns the Unix signal which terminated this process.

Note that on Windows this will always return None and on Unix this will return None if the process successfully exited otherwise.

For simplicity and to match wait_timeout, this method is always present even on systems that do not support it.
