[][src]Struct pallet_contracts::Module

pub struct Module<T: Trait>(_);

Contracts module.

Implementations

impl<T: Trait> Module<T>[src]

Can also be called using Call.

pub fn update_schedule(
    origin: <T as Trait>::Origin,
    schedule: Schedule
) -> DispatchResult
[src]

Updates the schedule for metering contracts.

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

NOTE: Calling this function will bypass origin filters.

pub fn put_code(origin: <T as Trait>::Origin, code: Vec<u8>) -> DispatchResult[src]

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

NOTE: Calling this function will bypass origin filters.

pub fn call(
    origin: <T as Trait>::Origin,
    dest: <T::Lookup as StaticLookup>::Source,
    value: BalanceOf<T>,
    gas_limit: Gas,
    data: Vec<u8>
) -> DispatchResultWithPostInfo
[src]

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.

NOTE: Calling this function will bypass origin filters.

pub fn instantiate(
    origin: <T as Trait>::Origin,
    endowment: BalanceOf<T>,
    gas_limit: Gas,
    code_hash: CodeHash<T>,
    data: Vec<u8>
) -> DispatchResultWithPostInfo
[src]

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.

NOTE: Calling this function will bypass origin filters.

impl<T: Trait> Module<T>[src]

Public APIs provided by the contracts module.

pub fn bare_call(
    origin: T::AccountId,
    dest: T::AccountId,
    value: BalanceOf<T>,
    gas_limit: Gas,
    input_data: Vec<u8>
) -> (ExecResult, Gas)
[src]

Perform a call to a specified contract.

This function is similar to Self::call, but doesn't perform any address lookups and better suitable for calling directly from Rust.

It returns the exection result and the amount of used weight.

pub fn get_storage(
    address: T::AccountId,
    key: [u8; 32]
) -> Result<Option<Vec<u8>>, ContractAccessError>
[src]

Query storage of a specified contract under a specified key.

pub fn rent_projection(
    address: T::AccountId
) -> Result<RentProjection<T::BlockNumber>, ContractAccessError>
[src]

impl<T: Trait + 'static> Module<T>[src]

pub fn current_schedule() -> Schedule[src]

Current cost schedule for contracts.
