Struct HypercallMmr 

pub struct HypercallMmr<S = MemoryMmrStore> {
    store: S,
    size: u64,
}

Self-contained MMR that owns its store.

Wraps the ckb MMR with its backing store so callers don’t have to manage store lifetimes. Exposes append + peaks_hash. Runtime code can provide a durable store; tests default to the in-memory store.

Fields

store: S

size: u64

Implementations

impl HypercallMmr<MemoryMmrStore>

pub fn new() -> Self

impl<S> HypercallMmr<S>

where S: PrepareMmrStore, for<'a> &'a S: MMRStoreReadOps<MmrHash> + MMRStoreWriteOps<MmrHash>,

pub fn from_store(store: S) -> Result<Self>

pub fn append(&mut self, data: [u8; 32]) -> Result<()>

Append a raw 32-byte hash as a leaf.

pub fn prepare_append_many( &self, data: &[[u8; 32]], ) -> Result<PreparedMmrAppend>

pub fn apply_prepared_append( &mut self, prepared: PreparedMmrAppend, ) -> Result<()>

pub fn peaks_hash(&self) -> MmrHash

Get the peaks hash (root commitment).

Returns a zero hash if the MMR is empty.

pub fn size(&self) -> u64

Trait Implementations

impl Default for HypercallMmr

fn default() -> Self
