Implementations

impl TransactionApi

pub fn remark(&self, remark: Vec<u8>) -> StaticTxPayload<Remark>

Make some on-chain remark.

• O(1)

pub fn set_heap_pages(&self, pages: u64) -> StaticTxPayload<SetHeapPages>

Set the number of pages in the WebAssembly environment’s heap.

pub fn set_code(&self, code: Vec<u8>) -> StaticTxPayload<SetCode>

Set the new runtime code.

• O(C + S) where C length of code and S complexity of can_set_code
• 1 call to can_set_code: O(S) (calls sp_io::misc::runtime_version which is expensive).
• 1 storage write (codec O(C)).
• 1 digest item.
• 1 event. The weight of this function is dependent on the runtime, but generally this is very expensive. We will treat this as a full block.

pub fn set_code_without_checks( &self, code: Vec<u8> ) -> StaticTxPayload<SetCodeWithoutChecks>

Set the new runtime code without doing any checks of the given code.

• O(C) where C length of code
• 1 storage write (codec O(C)).
• 1 digest item.
• 1 event. The weight of this function is dependent on the runtime. We will treat this as a full block. #

pub fn set_storage( &self, items: Vec<(Vec<u8>, Vec<u8>)> ) -> StaticTxPayload<SetStorage>

Set some items of storage.

pub fn kill_storage(&self, keys: Vec<Vec<u8>>) -> StaticTxPayload<KillStorage>

Kill some items from storage.

pub fn kill_prefix( &self, prefix: Vec<u8>, subkeys: u32 ) -> StaticTxPayload<KillPrefix>

Kill all storage items with a key that starts with the given prefix.

NOTE: We rely on the Root origin to provide us the number of subkeys under the prefix we are removing to accurately calculate the weight of this function.

pub fn remark_with_event( &self, remark: Vec<u8> ) -> StaticTxPayload<RemarkWithEvent>

Make some on-chain remark and emit event.
