Required Methods

fn key_value_entry_get( &mut self, handle: KeyValueEntryHandle, ) -> Result<Vec<u8>, E>

Reads the value of a key value entry

fn key_value_entry_set( &mut self, handle: KeyValueEntryHandle, buffer: Vec<u8>, ) -> Result<(), E>

Set the value of a key value entry

fn key_value_entry_remove( &mut self, handle: KeyValueEntryHandle, ) -> Result<Vec<u8>, E>

Remove the value of a key value entry

fn key_value_entry_lock(&mut self, handle: KeyValueEntryHandle) -> Result<(), E>

Lock the value of a key value entry making the value immutable

fn key_value_entry_close( &mut self, handle: KeyValueEntryHandle, ) -> Result<(), E>

Close the handle into the key value entry rendering it unusable after close

Provided Methods

fn key_value_entry_get_typed<S: ScryptoDecode>( &mut self, handle: KeyValueEntryHandle, ) -> Result<Option<S>, E>

Reads the value of a key value entry and decodes it into a specific type

fn key_value_entry_set_typed<S: ScryptoEncode>( &mut self, handle: KeyValueEntryHandle, value: S, ) -> Result<(), E>

Set the value of a key value entry

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.
