Enum PidRefusal 

pub enum PidRefusal {
    Zero,
    OutOfRange(u32),
    Init,
    OwnProcess(u32),
    OwnGroup(u32),
}

Why a PID may not be handed to a signal syscall.

Variants

Zero

kill(0, …) addresses the caller’s own process group.

OutOfRange(u32)

Above i32::MAX the value wraps to a negative pid_t: a process group, or (u32::MAX = -1) every process the user may signal.

Init

PID 1 is init (or a user’s systemd); never a LeanCTX target.

OwnProcess(u32)

The caller itself.

OwnGroup(u32)

The process group the caller belongs to.

impl Eq for PidRefusal

impl Error for PidRefusal

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.
