Trait DurabilityProvider 

pub trait DurabilityProvider<V>: Send + Debug
where
    V: Identities,
{
    // Required methods
    fn domains(&self) -> Vec<FlushDomain>;
    fn make_durable(&mut self, request: FlushRequest<V>);
}

A consumer-supplied durability provider. It makes writes the instance has seen complete durable, by any means, and answers per flush domain. An instance holds at most one; several are composed by a router that is itself a provider. Every other domain, and every file declared with none, is the built-in default’s.

Required Methods

fn domains(&self) -> Vec<FlushDomain>

The flush domains this provider serves, read once when the instance is built.

fn make_durable(&mut self, request: FlushRequest<V>)

Make the named writes durable. Returns promptly; the work may finish later, on any thread, through each domain’s completion – inside this call included. Holds no reference to the instance.

dioring calls it from the consumer’s own calls on the instance – normally the pop that follows the completion letting a seal start – and never with its lock held, so an answer given inside it is recorded at once (DI-D-44). A panic propagates to that call, and every completion it drops unanswered is a failure of its domain.

Dyn Compatibility

This trait is dyn compatible.

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