Required Methods§

Source

fn actor_sorted_index_insert( &mut self, object_handle: u32, collection_index: u8, sorted_key: ([u8; 2], Vec<u8>), buffer: Vec<u8>, ) -> Result<(), E>

Inserts an entry into a sorted index

Source

fn actor_sorted_index_remove( &mut self, object_handle: u32, collection_index: u8, sorted_key: &([u8; 2], Vec<u8>), ) -> Result<Option<Vec<u8>>, E>

Removes an entry from a sorted index

Source

fn actor_sorted_index_scan( &mut self, object_handle: u32, collection_index: u8, count: u32, ) -> Result<Vec<(([u8; 2], Vec<u8>), Vec<u8>)>, E>

Scans the first elements of count from a sorted index

Provided Methods§

Source

fn actor_sorted_index_insert_typed<V>( &mut self, object_handle: u32, collection_index: u8, sorted_key: ([u8; 2], Vec<u8>), value: V, ) -> Result<(), E>
where V: ScryptoEncode,

Inserts an entry into a sorted index

Source

fn actor_sorted_index_remove_typed<V>( &mut self, object_handle: u32, collection_index: u8, sorted_key: &([u8; 2], Vec<u8>), ) -> Result<Option<V>, E>
where V: ScryptoDecode,

Removes an entry from a sorted index

Source

fn actor_sorted_index_scan_typed<K, V>( &mut self, object_handle: u32, collection_index: u8, count: u32, ) -> Result<Vec<(K, V)>, E>
where K: ScryptoDecode, V: ScryptoDecode,

Scans the first elements of count from a sorted index

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.
