Struct RevealedSparseTrie

Source 
pub struct RevealedSparseTrie { /* private fields */ }
Expand description

The representation of revealed sparse trie.

§Invariants

  • The root node is always present in nodes collection.
  • Each leaf entry in nodes collection must have a corresponding entry in values collection. The opposite is also true.
  • All keys in values collection are full leaf paths.

Implementations§

Source§
