Enum RestartPolicy 

pub enum RestartPolicy {
    Always,
    OnFailure,
    Never,
}

Restart policy for a service managed by the supervisor.

Controls how the supervisor responds when a service exits unexpectedly.

Variants

Always

Always restart the service on failure (transient or permanent). The supervisor will apply exponential backoff between attempts.

OnFailure

Only restart on error returns. If the service exits with Ok(()), it is considered complete and will not be restarted.

Never

Never restart. The service runs once and the supervisor only logs its exit status. Useful for one-shot initialization tasks.

Trait Implementations

impl Clone for RestartPolicy

fn clone(&self) -> RestartPolicy

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RestartPolicy

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

Formats the value using the given formatter.

impl Default for RestartPolicy

fn default() -> RestartPolicy

Returns the “default value” for a type.

impl Display for RestartPolicy

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

Formats the value using the given formatter.

impl PartialEq for RestartPolicy

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