Enum Shutdown

pub enum Shutdown {
    Graceful,
    Forced,
    Crash,
}

Types of shutdown recognized by Abscissa

Variants

Graceful

Graceful shutdowns may take prolonged periods of time, allowing components to take their time to ensure shutdowns occur cleanly (e.g. draining currently active traffic rather than closing sockets)

Forced

Forced shutdowns indicate the program’s user has requested it terminate immediately. Components receiving this kind of shutdown should do only critical cleanup tasks which can be completed quickly.

Crash

This shutdown type is a “best effort” to communicate that the application has suffered from a critical error and is in the process of exiting. Components may use this to do crash reporting prior to the application exit, as well as any other cleanup deemed suitable within a crashing application.

Trait Implementations

impl Clone for Shutdown

fn clone(&self) -> Shutdown

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Shutdown

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Hash for Shutdown

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Shutdown

fn eq(&self, other: &Shutdown) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
