}

Extension trait that provides helper methods for calling NativeToken’s methods on Env for convenience purposes

Required Methods

fn native_token_initialize( &mut self, method_context: MethodContext, contract: Address, own_balance: &Address, max_issuance: &Balance, ) -> Result<NativeToken, ContractError>

Initialize native token on a shard with max issuance allowed by this shard.

Block rewards will be implemented using transfers from native token’s balance.

fn native_token_balance( &self, contract: Address, target: &Address, ) -> Result<Balance, ContractError>

fn native_token_transfer( &mut self, method_context: MethodContext, contract: Address, from: &Address, to: &Address, amount: &Balance, ) -> Result<(), ContractError>

Dyn Compatibility

This trait is dyn compatible.

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