Enum ExitReason 

pub enum ExitReason {
    Normal,
    Crashed(String),
    Runaway(String),
    Killed(String),
    Fatal(String),
}

Why a process stopped.

Variants

Normal

Ran to completion.

Crashed(String)

A typed runtime failure. Carries the rendered error.

Runaway(String)

The execution budget ran out — a runaway. This is the case that was previously an OS-process abort, and it is the reason supervision is possible at all.

Killed(String)

Ended from outside: an exit signal from a linked process, exit(pid, reason), or a supervisor shutting its children down. Carries the rendered reason.

Fatal(String)

A fault the runtime declares unrecoverable, such as a capability breach. Links and monitors see it; a supervisor never restarts it.

Implementations

impl ExitReason

pub fn memory_exhausted(bound: u64) -> Self

A process that held more than bound live bytes: a runaway, which its links, monitors and supervisor see, and a supervisor restarts.

pub fn dispatch_exhausted(limit: usize) -> Self

pub fn is_abnormal(&self) -> bool

pub fn is_fatal(&self) -> bool

pub fn is_restartable(&self) -> bool

Does a supervisor restart a child that exited this way?
