Variants

fill_block

Fields

ratio: Perbill

A dispatch that will fill the block weight up to the given ratio.

remark

Fields

remark: Vec<u8>

Make some on-chain remark.

• O(1)

set_heap_pages

Fields

pages: u64

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

set_code

Fields

code: Vec<u8>

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.

set_code_without_checks

Fields

code: Vec<u8>

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. #

set_storage

Fields

items: Vec<KeyValue>

Set some items of storage.

kill_storage

Fields

keys: Vec<Key>

Kill some items from storage.

kill_prefix

Fields

prefix: Key

subkeys: u32

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.

remark_with_event

Fields

remark: Vec<u8>

Make some on-chain remark and emit event.

• O(b) where b is the length of the remark.
• 1 event.
