Trait BlockchainAPI

pub trait BlockchainAPI {
    // Required methods
    fn get_param(&self, param_id: u32) -> Result<Vec<u8>, HostError>;
    fn as_any(&mut self) -> &mut dyn Any;
}

the blockchain APIs that should be provided by the host. It can’t be copied or cloned since it doesn’t have Copy and Clone traits.

Required Methods

fn get_param(&self, param_id: u32) -> Result<Vec<u8>, HostError>

This API requests the host to return the associated value to the given param_id.

fn as_any(&mut self) -> &mut dyn Any

It is useful for downcasting the trait to the underling struct. For example we can downcast the trait to the mocked object.
