}

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

Required Methods

fn code_deploy( &mut self, method_context: MethodContext, contract: Address, code: &VariableBytes<'_, MAX_CODE_SIZE>, ) -> Result<Address, ContractError>

Deploy a new contract with specified code

fn code_store( &mut self, method_context: MethodContext, contract: Address, contract_code: &Address, new_code: &VariableBytes<'_, MAX_CODE_SIZE>, ) -> Result<(), ContractError>

Store contact’s code overriding previous code that might have been there.

Updates can only be done by the contract itself with direct calls.

fn code_read<'code>( &self, contract: Address, contract_code: &Address, code: &mut impl OutputArg<VariableBytes<'code, MAX_CODE_SIZE>>, ) -> Result<(), ContractError>

Read contract’s code

Dyn Compatibility

This trait is not dyn compatible.

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

Implementations on Foreign Types

impl CodeExt for Env<'_>
