Trait DatastoreExt 

pub(crate) trait DatastoreExt<'a>: Copy {
    // Required methods
    fn reader<T>(self) -> Reader<'a, T>
       where T: Storable + 'static;
    fn exclusive_reader<T>(self) -> ExclusiveReader<'a, T>
       where T: Storable + 'static;
    fn writer<T>(self) -> Writer<'a, T>
       where T: Storable + 'static;
}

Required Methods

fn reader<T>(self) -> Reader<'a, T>

where T: Storable + 'static,

Returns the Reader for a specific slot.

Panics

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

fn exclusive_reader<T>(self) -> ExclusiveReader<'a, T>

where T: Storable + 'static,

Returns the ExclusiveReader for a specific slot.

Exclusivity of the reader is not guaranteed by this method and must be ensured via other means (e.g. crate::execute::validate_actors).

Panics

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

fn writer<T>(self) -> Writer<'a, T>

where T: Storable + 'static,

Returns the Writer for a specific slot.

Panics

• If the Writer for this slot has already been acquired.

• 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.
