Expand description
Unix-specific extensions to process::ExitStatus andExitStatusError.
On Unix, ExitStatus does not necessarily represent an exit status, as passed to the _exit system call or returned byExitStatus::code(). It represents any wait statusas returned by one of the wait family of system calls.
A Unix wait status (a Rust ExitStatus) can represent a Unix exit status, but can also represent other kinds of process event.
This trait is sealed: it cannot be implemented outside the standard library. This is so that future additional methods are not breaking changes.

Creates a new ExitStatus or ExitStatusError from the raw underlying integer status value from wait
The value should be a wait status, not an exit status.
§Panics
Panics on an attempt to make an ExitStatusError from a wait status of 0.
Making an ExitStatus always succeeds and never panics.

If the process was terminated by a signal, returns that signal.
In other words, if WIFSIGNALED, this returns WTERMSIG.

If the process was terminated by a signal, says whether it dumped core.

If the process was stopped by a signal, returns that signal.
In other words, if WIFSTOPPED, this returns WSTOPSIG. This is only possible if the status came from a wait system call which was passed WUNTRACED, and was then converted into an ExitStatus.

Whether the process was continued from a stopped status.
Ie, WIFCONTINUED. This is only possible if the status came from a wait system call which was passed WCONTINUED, and was then converted into an ExitStatus.

Returns the underlying raw wait status.
The returned integer is a wait status, not an exit status.
This trait is not dyn compatible.
In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
