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<HashMap<FixedBytes<32>, Bytes, FbBuildHasher<32>>, TrieWitnessError>;
}

Available on crate features trie and trie-db only.

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<HashMap<FixedBytes<32>, Bytes, FbBuildHasher<32>>, 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.

Implementors

impl<'a, TX> DatabaseTrieWitness<'a, TX> for TrieWitness<DatabaseTrieCursorFactory<&'a TX>, DatabaseHashedCursorFactory<&'a TX>>

where TX: DbTx,
