This trait serves as a primary interface for interacting with smart contracts.

Required Methods

fn instantiate( &self, deps: DepsMut<'_, Q>, env: Env, info: MessageInfo, msg: Vec<u8>, ) -> StdResult<Response<C>>

Evaluates contract’s execute entry-point.

fn query(&self, deps: Deps<'_, Q>, env: Env, msg: Vec<u8>) -> StdResult<Binary>

Evaluates contract’s query entry-point.

fn reply( &self, deps: DepsMut<'_, Q>, env: Env, msg: Reply, ) -> StdResult<Response<C>>

Evaluates contract’s reply entry-point.

fn sudo( &self, deps: DepsMut<'_, Q>, env: Env, msg: Vec<u8>, ) -> StdResult<Response<C>>

Evaluates contract’s sudo entry-point.

fn migrate( &self, deps: DepsMut<'_, Q>, env: Env, msg: Vec<u8>, info: MigrateInfo, ) -> StdResult<Response<C>>
