}
Expand description

Converts between key+data entries and an entity object.

This trait is used for entity bindings where the key and data are stored separately but represent a single logical entity.

Required Methods§

Source

fn entry_to_object( &self, key: &DatabaseEntry, data: &DatabaseEntry, ) -> Result<E>

Converts key and data entries to an entity object.

§Errors

Returns BindError if the entries cannot be deserialized.

Source

fn object_to_key(&self, object: &E, key: &mut DatabaseEntry) -> Result<()>

Extracts the key from an entity object and writes it to a DatabaseEntry.

§Errors

Returns BindError if the key cannot be serialized.

Source

fn object_to_data(&self, object: &E, data: &mut DatabaseEntry) -> Result<()>

Extracts the data from an entity object and writes it to a DatabaseEntry.

§Errors

Returns BindError if the data cannot be serialized.

Dyn Compatibility§

This trait is dyn compatible.

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