Struct fuel_core_storage::blueprint::merklized::Merklized

source · 
pub struct Merklized<KeyCodec, ValueCodec, Metadata, Nodes, ValueEncoder> { /* private fields */ }
Expand description

The Merklized blueprint builds the storage as a Plain blueprint and maintains the binary merkle tree by the Metadata table.

It uses the KeyCodec and ValueCodec to encode/decode the key and value in the same way as a plain blueprint.

The Metadata table stores the metadata of the binary merkle tree(like a root of the tree and leaves count).

The ValueEncoder is used to encode the value for merklelization.
