ProofV2TargetParent

reth_trie_common::target_v2

Struct ProofV2TargetParent 

Source 
pub struct ProofV2TargetParent(/* private fields */);
Expand description

The already-revealed parent branch of a ProofV2Target.

Self::NONE indicates that no parent is known and the proof must include the actual trie root. A known parent at path length n makes the proof start at its direct child at length n + 1. In particular, a known parent at path length zero means the root branch is already revealed, so the proof starts at one of its direct children. Known parent path lengths are always less than 64.

Parent contexts are ordered from broadest to narrowest: Self::NONE precedes every known parent, and known parents are ordered by path length.
