Expand description
Trait to configure the creation of a Backend
.
Should contain options used to create a specific backend. When a container is created, this trait is used to create the related backend.
The Create::settings()
method returns an instance of the settings of
this backend instance. The settings contains runtime configuration used by
the backend. The container stores the settings (possibly encrypted) in the
header of the container and should contain all settings/information needed
by the backend. It is loaded again from the header when the container is
opened.
Any type that implements this Create
trait must also implement the
HeaderSet
trait because the header of the container is created here.
Finally, the container calls Create::build()
to create an instance of the
Backend
. The resulting backend instance should be able to handle all
operations on it. The Create::build()
method should validate all its
settings before returning the backend instance!
Required Methods§
sourcefn settings(&self) -> B::Settings
fn settings(&self) -> B::Settings
Returns the settings of this backend instance.
The settings contains runtime configuration used by the backend. The container stores the settings (possibly encrypted) in the header of the container and should contain all settings/information needed by the backend. It is loaded again from the header when the container is opened.
sourcefn build(self) -> Result<B, B::Err>
fn build(self) -> Result<B, B::Err>
Create an instance of the Backend
.
The container calls Create::build()
to create an instance of the
Backend
. The resulting backend instance should be able to handle
all operations on it. The Create::build()
method should validate
all its settings before returning the backend instance!
