Available on crate features
trie
and trie-db
only.Expand description
Extends TrieWitness
with operations specific for working with a database transaction.
Required Methods§
fn from_tx(tx: &'a TX) -> Self
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>
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.
