Trait ink_storage_traits::StorageLayout

pub trait StorageLayout {
    // Required method
    fn layout(key: &Key) -> Layout;
}

Implemented by types that have a storage layout.

Required Methods

fn layout(key: &Key) -> Layout

Returns the static storage layout of Self.

The given storage key is guiding the allocation of static fields onto the contract storage regions.

Object Safety

This trait is not object safe.
