Struct Sparse

source 
pub struct Sparse<KeyCodec, ValueCodec, Metadata, Nodes, KeyConverter> { /* private fields */ }
Expand description

The Sparse blueprint builds the storage as a Plain blueprint and maintains the sparse merkle tree by the Metadata and Nodes tables.

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 tree(like a root of the tree), and the Nodes table stores the tree’s nodes. The SMT is built over the encoded keys and values using the same encoding as for main key-value pairs.

The KeyConverter is used to convert the key of the table into the primary key of the metadata table.
