Trait ink_storage::traits::PackedLayout

pub trait PackedLayout: SpreadLayout + Encode + Decode {

}

Types that can be stored to and loaded from a single contract storage cell.

Required methods

fn pull_packed(&mut self, at: &Key)

Indicates to self that is has just been pulled from the storage.

Note

Most types will have to implement a simple forwarding to their fields. However, some types such as storage::Box are required to perform some special handling upon receiving this signal.

fn push_packed(&self, at: &Key)

Indicates to self that it is about to be pushed to contract storage.

Note

Most types will have to implement a simple forwarding to their fields. However, some types such as storage::Box are required to perform some special handling upon receiving this signal.

fn clear_packed(&self, at: &Key)

Indicates to self that it is about to be cleared from contract storage.

Note

Most types will have to implement a simple forwarding to their fields. However, some types such as storage::Box are required to perform some special handling upon receiving this signal.
