Enum AutoShutdown 

pub enum AutoShutdown {
    Never,
    AnySignificant,
    AllSignificant,
}

Policy for automatically shutting a supervisor down based on the termination of its significant children.

A significant child (see ChildSpecification::with_significant) is one whose termination – when it isn’t restarted – can drive the supervisor to shut down. This mirrors Erlang/OTP’s auto_shutdown supervisor flag, and is how an unexpected (or intentional) child exit cascades into the supervisor stopping, and thus propagating up the tree, without that child being restarted.

Variants

Never

Never shut down automatically; significant children have no special effect. This is the default.

AnySignificant

Shut down as soon as any significant child terminates without being restarted.

AllSignificant

Shut down once all significant children have terminated without being restarted.

Trait Implementations

impl Clone for AutoShutdown

fn clone(&self) -> AutoShutdown

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for AutoShutdown

impl Debug for AutoShutdown

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

Formats the value using the given formatter.

impl Default for AutoShutdown

fn default() -> AutoShutdown

Returns the “default value” for a type.

impl Eq for AutoShutdown

impl PartialEq for AutoShutdown

fn eq(&self, other: &AutoShutdown) -> 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.
