pub struct Memory<T> { /* private fields */ }
Expand description

An instance that is solely stored within the contract’s memory.

This will never be stored to or loaded from contract storage.

Note

Use instances of this type in order to have some shared state between contract messages and functions. Its usage is comparable to the Solidity’s memory instances. Pulling an instance of this type from the contract storage will always yield a default constructed value.

Implementations

Creates a new memory instance.

Returns a shared reference to the inner T.

Returns an exclusive reference to the inner T.

Indicates whether a type requires deep clean-up of its state meaning that a clean-up routine has to decode an entity into an instance in order to eventually recurse upon its tear-down. This is not required for the majority of primitive data types such as i32, however types such as storage::Box that might want to forward the clean-up procedure to their inner T require a deep clean-up.
