struct, the main type that implements traits and standalone
functions within the pallet.
Implementations§
source§impl<T: Config<I>, I: 'static> Pallet<T, I>
impl<T: Config<I>, I: 'static> Pallet<T, I>
sourcepub fn mmr_leaves() -> LeafIndex
pub fn mmr_leaves() -> LeafIndex
An auto-generated getter for NumberOfLeaves
.
source§impl<T: Config<I>, I: 'static> Pallet<T, I>
impl<T: Config<I>, I: 'static> Pallet<T, I>
sourcepub fn block_num_to_leaf_count(
block_num: BlockNumberFor<T>,
) -> Result<LeafIndex, Error>where
T: Config,
pub fn block_num_to_leaf_count(
block_num: BlockNumberFor<T>,
) -> Result<LeafIndex, Error>where
T: Config,
Convert a block number into a leaf index.
sourcepub fn generate_proof(
block_numbers: Vec<BlockNumberFor<T>>,
best_known_block_number: Option<BlockNumberFor<T>>,
) -> Result<(Vec<<<T as Config<I>>::LeafData as LeafDataProvider>::LeafData>, LeafProof<<<T as Config<I>>::Hashing as Hash>::Output>), Error>
pub fn generate_proof( block_numbers: Vec<BlockNumberFor<T>>, best_known_block_number: Option<BlockNumberFor<T>>, ) -> Result<(Vec<<<T as Config<I>>::LeafData as LeafDataProvider>::LeafData>, LeafProof<<<T as Config<I>>::Hashing as Hash>::Output>), Error>
Generate an MMR proof for the given block_numbers
.
If best_known_block_number = Some(n)
, this generates a historical proof for
the chain with head at height n
.
Else it generates a proof for the MMR at the current block height.
Note this method can only be used from an off-chain context (Offchain Worker or Runtime API call), since it requires all the leaves to be present. It may return an error or panic if used incorrectly.
sourcepub fn verify_leaves(
leaves: Vec<<<T as Config<I>>::LeafData as LeafDataProvider>::LeafData>,
proof: LeafProof<<<T as Config<I>>::Hashing as Hash>::Output>,
) -> Result<(), Error>
pub fn verify_leaves( leaves: Vec<<<T as Config<I>>::LeafData as LeafDataProvider>::LeafData>, proof: LeafProof<<<T as Config<I>>::Hashing as Hash>::Output>, ) -> Result<(), Error>
Verify MMR proof for given leaves
.
This method is safe to use within the runtime code.
It will return Ok(())
if the proof is valid
and an Err(..)
if MMR is inconsistent (some leaves are missing)
or the proof is invalid.
pub fn generate_ancestry_proof( prev_block_number: BlockNumberFor<T>, best_known_block_number: Option<BlockNumberFor<T>>, ) -> Result<AncestryProof<<<T as Config<I>>::Hashing as Hash>::Output>, Error>
