Trait Invariant

Source 
pub trait Invariant {
    type InternalState: 'static + Send + Default;

    // Required methods
    fn triggers(&self) -> &[ActionKind];
    fn check<S: Service>(
        self,
        internal_state: &mut Self::InternalState,
        store: &Store<S>,
        action: &ActionWithMeta,
    ) -> InvariantResult;

    // Provided method
    fn is_global(&self) -> bool { ... }
}

Required Associated Types§

Source

type InternalState: 'static + Send + Default

Internal state of the invariant.

If some state needs to be preserved across checks, this is the place.

Required Methods§

Source

fn triggers(&self) -> &[ActionKind]

Invariant triggers define a list actions, which should cause Invariant::check to be called.

If empty, an invariant will never be checked!

Source

fn check<S: Service>( self, internal_state: &mut Self::InternalState, store: &Store<S>, action: &ActionWithMeta, ) -> InvariantResult

Checks the state for invariant violation.

Provided Methods§

Source

fn is_global(&self) -> bool

Whether or not invariant is cluster-wide, or for just local node.

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
