Trait RetentionStore 

pub trait RetentionStore: Send + Sync {
    // Required methods
    fn retention_preview<'a>(
        &'a self,
        scope: &'a Scope,
        policy: &'a RetentionPolicy,
        deadline: Instant,
    ) -> ContractFuture<'a, RetentionPreview>;
    fn retain_batch<'a>(
        &'a self,
        scope: &'a Scope,
        policy: &'a RetentionPolicy,
        deadline: Instant,
    ) -> ContractFuture<'a, RetentionProgress>;
}

Required Methods

fn retention_preview<'a>( &'a self, scope: &'a Scope, policy: &'a RetentionPolicy, deadline: Instant, ) -> ContractFuture<'a, RetentionPreview>

fn retain_batch<'a>( &'a self, scope: &'a Scope, policy: &'a RetentionPolicy, deadline: Instant, ) -> ContractFuture<'a, RetentionProgress>

Cooperating calls must preserve live cursors, active execution trees and unfinished delivery/reconciliation obligations. Crash/retry can repeat a batch; progress counts only the transaction acknowledged by this call.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
