}Expand description
Unix-specific extensions to process::ExitStatus and
ExitStatusError.
On Unix, ExitStatus does not necessarily represent an exit status, as
passed to the _exit system call or returned by
ExitStatus::code(). It represents any wait status
as 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.
Required Methods§
1.12.0 · Sourcefn from_raw(raw: i32) -> Self
fn from_raw(raw: i32) -> Self
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.
1.0.0 · Sourcefn signal(&self) -> Option<i32>
fn signal(&self) -> Option<i32>
If the process was terminated by a signal, returns that signal.
In other words, if WIFSIGNALED, this returns WTERMSIG.
1.58.0 · Sourcefn core_dumped(&self) -> bool
fn core_dumped(&self) -> bool
If the process was terminated by a signal, says whether it dumped core.
1.58.0 · Sourcefn stopped_signal(&self) -> Option<i32>
fn stopped_signal(&self) -> Option<i32>
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.
Dyn Compatibility§
This trait is not dyn compatible.
In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
