Path

Struct Path 

Source
pub struct Path {
    pub nodes: Vec<Cid>,
    pub value: Option<Cid>,
}
Expand description

Which blocks prove what a tree says about one key.

The nodes are the walk from the root down, in that order, and each one names the next: a verifier hashes each block to check it is the node it was told to expect, reads the entry range it lands in, and follows the link. value is the record’s CID when the key is in the tree and None when it is not — and the absence is proved by the same nodes, because the last one on the path is where the key would have to be if it existed.

Fields§

§nodes: Vec<Cid>

The nodes walked, root first.

§value: Option<Cid>

The record the key names, if the tree holds it.

impl PartialEq for Path

Source§

fn eq(&self, other: &Path) -> bool
