Struct clearStorageCall

pub struct clearStorageCall {
    pub flags: u32,
    pub isFixedKey: bool,
    pub key: Bytes,
}

Clear the value at the given key in the contract storage.

Important

This function can only be called via a delegate call! For Solidity, the low level delegatecall function has to be used. For languages that use the FFI of pallet-revive, the crate::HostFn::delegate_call function can be used.

Parameters

• key: The storage key.

Return

If no entry existed for this key, containedKey is false and valueLen is 0. Function with signature clearStorage(uint32,bool,bytes) and selector 0xccecf715.

function clearStorage(uint32 flags, bool isFixedKey, bytes memory key) external returns (bool containedKey, uint valueLen);

Fields

flags: u32

isFixedKey: bool

key: Bytes
