Trait DatabaseTrieWitness

pub trait DatabaseTrieWitness<'a, TX> {
    // Required methods
    fn from_tx(tx: &'a TX) -> Self;
    fn overlay_witness(
        tx: &'a TX,
        input: TrieInput,
        target: HashedPostState,
    ) -> Result<B256HashMap<Bytes>, TrieWitnessError>;
}

Extends [TrieWitness] with operations specific for working with a database transaction.

Required Methods

fn from_tx(tx: &'a TX) -> Self

Create a new [TrieWitness] from database transaction.

fn overlay_witness( tx: &'a TX, input: TrieInput, target: HashedPostState, ) -> Result<B256HashMap<Bytes>, TrieWitnessError>

Generates trie witness for target state based on [TrieInput].

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
