Source§impl<'api> SystemPagedQueryApi<'api>
impl<'api> SystemPagedQueryApi<'api>
Sourcepub fn account(&self) -> StoragePaged<AccountId, AccountInfo<u32, AccountData>>
pub fn account(&self) -> StoragePaged<AccountId, AccountInfo<u32, AccountData>>
The full account information for a particular account ID.
Sourcepub fn block_hash(&self) -> StoragePaged<u32, H256>
pub fn block_hash(&self) -> StoragePaged<u32, H256>
Map of block numbers to block hashes.
Sourcepub fn extrinsic_data(&self) -> StoragePaged<u32, Vec<u8>>
pub fn extrinsic_data(&self) -> StoragePaged<u32, Vec<u8>>
Extrinsics data for the current block (maps an extrinsic’s index to its data).
Sourcepub fn event_topics(&self) -> StoragePaged<H256, Vec<(u32, u32)>>
pub fn event_topics(&self) -> StoragePaged<H256, Vec<(u32, u32)>>
Mapping between a topic (represented by T::Hash) and a vector of indexes
of events in the <Events<T>> list.
All topic vectors have deterministic storage locations depending on the topic. This allows light-clients to leverage the changes trie storage tracking mechanism and in case of changes fetch the list of events of interest.
The value has the type (T::BlockNumber, EventIndex) because if we used only just
the EventIndex then in case if the topic has the same contents on the next block
no notification will be triggered thus the event might be lost.
