Expand description

Light client blockchain.

Implementations

Create new light blockchain backed with given storage.

Get storage reference.

Trait Implementations

Get block body. Returns None if block is not found.

Get block justifications. Returns None if no justification exists.

Get last finalized block hash.

Returns data cache reference, if it is enabled on this backend.

Returns hashes of all blocks that are leaves of the block tree. in other words, that have no children, are chain heads. Results must be ordered best (longest, highest) chain first. Read more

Return hashes of all blocks that are children of the block with parent_hash.

Get single indexed transaction by content hash. Note that this will only fetch transactions that are indexed by the runtime with storage_index_transaction. Read more

Get the most recent block hash of the best (longest) chains that contain block with the given target_hash. Read more

Check if indexed transaction exists.

Get block header. Returns None if block is not found.

Get blockchain info.

Get block status.

Get block number by hash. Returns None if the header is not in the chain.

Get block hash by number. Returns None if the header is not in the chain.

Convert an arbitrary block ID into a block hash.

Convert an arbitrary block ID into a block hash.

Get block header. Returns UnknownBlock error if block is not found.

Convert an arbitrary block ID into a block number. Returns UnknownBlock error if block is not found. Read more

Convert an arbitrary block ID into a block hash. Returns UnknownBlock error if block is not found. Read more

Error used in case the header metadata is not found.

Returns data cache reference, if it is enabled on this backend.

Get headers CHT root for given block. Returns None if the block is not a part of any CHT.

Get changes trie CHT root for given block. Returns None if the block is not a part of any CHT. Read more

Get block header.
