Type Alias concordium_std::InitResult

source ·
pub type InitResult<S> = Result<S, Reject>;
Expand description

The expected return type of the init method of the smart contract, parametrized by the state type of the smart contract.

Optionally, to define a custom type for error instead of using Reject, allowing the track the reason for rejection.

See also the documentation for bail! for how to use custom error types.

§Example

Defining a custom error type that implements Reject and Serial.

#[derive(Serial, Reject)]
enum MyCustomError {
    SomeError,
}

#[init(contract = "mycontract")]
fn contract_init(
    _ctx: &InitContext,
    _state_builder: &mut StateBuilder,
) -> Result<(), MyCustomError> {
    Err(MyCustomError::SomeError)
}
