Expand description

Represents the static storage layout of an ink! smart contract.

Variants

Leaf(LeafLayout<F>)

An encoded cell.

This is the only leaf node within the layout graph. All layout nodes have this node type as their leafs.

Root(RootLayout<F>)

The root cell defines the storage key for all sub-trees.

Hash(HashLayout<F>)

A layout that hashes values into the entire storage key space.

This is commonly used by ink! hashmaps and similar data structures.

Array(ArrayLayout<F>)

An array of type associated with storage cell.

Struct(StructLayout<F>)

A struct layout with fields of different types.

Enum(EnumLayout<F>)

An enum layout with a discriminant telling which variant is layed out.
