Struct SystemCallApi

pub struct SystemCallApi<'api> { /* private fields */ }

Implementations

impl<'api> SystemCallApi<'api>

pub fn remark(&self, remark: Vec<u8>) -> Result<WrappedCall>

Make some on-chain remark.

Complexity

• O(1)

pub fn set_heap_pages(&self, pages: u64) -> Result<WrappedCall>

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

pub fn set_code(&self, code: Vec<u8>) -> Result<WrappedCall>

Set the new runtime code.

Complexity

• O(C + S) where C length of code and S complexity of can_set_code

pub fn set_code_without_checks(&self, code: Vec<u8>) -> Result<WrappedCall>

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

Complexity

• O(C) where C length of code

pub fn set_storage(&self, items: Vec<(Vec<u8>, Vec<u8>)>) -> Result<WrappedCall>

Set some items of storage.

pub fn kill_storage(&self, keys: Vec<Vec<u8>>) -> Result<WrappedCall>

Kill some items from storage.

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

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>) -> Result<WrappedCall>

Make some on-chain remark and emit event.
