Implementations

impl<T, I> Pallet<T, I>

where T: Config<I>, I: 'static,

pub fn mmr_leaves() -> u64

An auto-generated getter for NumberOfLeaves.

impl<T, I> Pallet<T, I>

where T: Config<I>, I: 'static,

pub fn mmr_peak<KArg>( k: KArg, ) -> Option<<<T as Config<I>>::Hashing as Hash>::Output>

where KArg: EncodeLike<u64>,

An auto-generated getter for Nodes.

impl<T, I> Pallet<T, I>

where T: Config<I>, I: 'static,

pub fn block_num_to_leaf_count( block_num: <<<T as Config>::Block as HeaderProvider>::HeaderT as Header>::Number, ) -> Result<u64, Error>

where T: Config,

Convert a block number into a leaf index.

pub fn generate_proof( block_numbers: Vec<<<<T as Config>::Block as HeaderProvider>::HeaderT as Header>::Number>, best_known_block_number: Option<<<<T as Config>::Block as HeaderProvider>::HeaderT as Header>::Number>, ) -> 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.

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: <<<T as Config>::Block as HeaderProvider>::HeaderT as Header>::Number, best_known_block_number: Option<<<<T as Config>::Block as HeaderProvider>::HeaderT as Header>::Number>, ) -> Result<AncestryProof<<<T as Config<I>>::Hashing as Hash>::Output>, Error>

pub fn generate_mock_ancestry_proof() -> Result<AncestryProof<<<T as Config<I>>::Hashing as Hash>::Output>, Error>

pub fn is_ancestry_proof_optimal( ancestry_proof: &AncestryProof<<<T as Config<I>>::Hashing as Hash>::Output>, ) -> bool

pub fn mmr_root() -> <<T as Config<I>>::Hashing as Hash>::Output

Return the on-chain MMR root hash.
