Type Alias concordium_std::ReceiveResult
source · pub type ReceiveResult<A> = Result<A, Reject>;Expand description
The expected return type of the receive method of a smart contract.
Optionally, to define a custom type for error instead of using Reject, allowing to 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,
}
#[receive(contract = "mycontract", name = "receive")]
fn contract_receive(_ctx: &ReceiveContext, _host: &Host<()>) -> Result<(), MyCustomError> {
Err(MyCustomError::SomeError)
}Aliased Type§
enum ReceiveResult<A> {
Ok(A),
Err(Reject),
}
