[−][src]Trait proof::MerkleTreeOverlay

pub trait MerkleTreeOverlay {
    fn get_node(path: Vec<Path>) -> Result<Node, Error>;
    fn height() -> u64;
    fn min_repr_size() -> u64;
}

Defines an interface for interacting with Proofs via Paths.

Required methods

`fn get_node(path: Vec<Path>) -> Result<Node, Error>`

Returns the Node coresponding to the path.

This will match path[0] against a field in the current object and recusively call itself on that field's type with path[1..] until the path is exhausted.

See the SSZ specification to better understand the tree architecture: https://github.com/ethereum/eth2.0-specs/blob/dev/specs/light_client/merkle_proofs.md Returns the Node coresponding to the given path.

`fn height() -> u64`

Returns the height of the merkle tree.

`fn min_repr_size() -> u64`

Returns the minimum number of bytes needed to represent the type's value.
