impl<H: Hasher> NodeCodec for NodeCodec<H>
sourcefn hashed_null_node() -> <H as Hasher>::Out
fn hashed_null_node() -> <H as Hasher>::Out
Get the hashed null node.
sourcefn decode_plan(data: &[u8]) -> Result<NodePlan, Self::Error>
fn decode_plan(data: &[u8]) -> Result<NodePlan, Self::Error>
Decode bytes to a NodePlan. Returns Self::E on failure.
sourcefn is_empty_node(data: &[u8]) -> bool
fn is_empty_node(data: &[u8]) -> bool
Check if the provided bytes correspond to the codecs “empty” node.
