Trait HandleCallback 

pub trait HandleCallback: Serialize {
    const BLOCK_SIZE: usize;

    // Provided method
    fn to_cosmos_msg(
        &self,
        code_hash: String,
        contract_addr: String,
        funds_amount: Option<Uint128>,
    ) -> StdResult<CosmosMsg> { ... }
}

A trait marking types that define the handle message(s) of a contract

This trait requires specifying a padding block size and provides a method to create the CosmosMsg used to execute a handle method of a contract

Required Associated Constants

const BLOCK_SIZE: usize

pad the message to blocks of this size

Provided Methods

fn to_cosmos_msg( &self, code_hash: String, contract_addr: String, funds_amount: Option<Uint128>, ) -> StdResult<CosmosMsg>

Returns StdResult

Tries to convert the instance of the implementing type to a CosmosMsg that will trigger a handle function of a contract. The BLOCK_SIZE specified in the implementation is used when padding the message

Arguments

• code_hash - String holding the code hash of the contract to be executed
• contract_addr - address of the contract being called
• funds_amount - Optional Uint128 amount of native coin to send with the handle message

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
