Trait Datastore 

pub trait Datastore {
    // Required methods
    fn source(self: Pin<&Self>) -> Pin<&Source>;
    fn slot<T>(self: Pin<&Self>) -> Pin<&Slot<T>>
       where T: Storable + 'static;
}

Internal trait to abstract out type-erased and concrete data stores.

Required Methods

fn source(self: Pin<&Self>) -> Pin<&Source>

Returns a generational source tracking the global datastore generation.

This is used to ensure that every reader has had (or will have) a chance to read a value before a writer may overwrite it.

fn slot<T>(self: Pin<&Self>) -> Pin<&Slot<T>>

where T: Storable + 'static,

Returns a reference to the slot for a specific type.

Panics

• If there is no Slot for T in the Datastore.

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.

Implementations on Foreign Types

impl<S> Datastore for Pin<&S>

where S: Datastore,

fn source(self: Pin<&Self>) -> Pin<&Source>

fn slot<T>(self: Pin<&Self>) -> Pin<&Slot<T>>

where T: Storable + 'static,

Implementors

impl<S> Datastore for Cons<Source, S>

where S: Slots,

Given a slot cons-list, combines it with a generational::Source to implement Datastore.
