Dispatchable calls.

Each variant of this enum maps to a dispatchable function from the associated module.

Variants

update_schedule(Schedule)

Updates the schedule for metering contracts.

The schedule must have a greater version than the stored schedule.

put_code(Vec<u8>)

Stores the given binary Wasm code into the chain's storage and returns its codehash. You can instantiate contracts only with stored code.

call(<T::Lookup as StaticLookup>::Source, BalanceOf<T>, Gas, Vec<u8>)

Makes a call to an account, optionally transferring some balance.

• If the account is a smart-contract account, the associated code will be executed and any value will be transferred.
• If the account is a regular account, any value will be transferred.
• If no account exists and the call value is not less than existential_deposit, a regular account will be created and any value will be transferred.

instantiate(BalanceOf<T>, Gas, CodeHash<T>, Vec<u8>)

Instantiates a new contract from the codehash generated by put_code, optionally transferring some balance.

Instantiation is executed as follows:

• The destination address is computed based on the sender and hash of the code.
• The smart-contract account is created at the computed address.
• The ctor_code is executed in the context of the newly-created account. Buffer returned after the execution is saved as the code of the account. That code will be invoked upon any call received by this account.
• The contract is initialized.

claim_surcharge(T::AccountId, Option<T::AccountId>)

Allows block producers to claim a small reward for evicting a contract. If a block producer fails to do so, a regular users will be allowed to claim the reward.

If contract is not evicted as a result of this call, no actions are taken and the sender is not eligible for the reward.
