Expand description

Return type for ‘view’ contract method

User is responsible for providing View and Error types. To use them with #[warp_contract(view)] macro they both have to implement Debug and Serialize. This allows passing them from rust to js.

Variants§

§

Success(View)

returned on success - View contains the result

§

ContractError(Error)

returned when a ‘business’ error occurred, The user-defined Error parameter is returned to the caller

§

RuntimeError(String)

returned when an unexpected error occurred, The String parameter is for debugging purposes
