Interface to call into a Contract.

Required Methods

fn execute( &self, deps: DepsMut<'_, Q>, env: Env, info: MessageInfo, msg: Vec<u8>, fork_state: ForkState<T, Q>, ) -> AnyResult<Response<T>>

fn instantiate( &self, deps: DepsMut<'_, Q>, env: Env, info: MessageInfo, msg: Vec<u8>, fork_state: ForkState<T, Q>, ) -> AnyResult<Response<T>>

fn query( &self, deps: Deps<'_, Q>, env: Env, msg: Vec<u8>, fork_state: ForkState<T, Q>, ) -> AnyResult<Binary>

fn sudo( &self, deps: DepsMut<'_, Q>, env: Env, msg: Vec<u8>, fork_state: ForkState<T, Q>, ) -> AnyResult<Response<T>>

fn reply( &self, deps: DepsMut<'_, Q>, env: Env, msg: Reply, fork_state: ForkState<T, Q>, ) -> AnyResult<Response<T>>

fn migrate( &self, deps: DepsMut<'_, Q>, env: Env, msg: Vec<u8>, fork_state: ForkState<T, Q>, ) -> AnyResult<Response<T>>

Provided Methods

fn checksum(&self) -> Option<Checksum>

Returns the provided checksum of the contract’s Wasm blob.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
