Trait rustracts::Contract

pub trait Contract: Future {
    fn is_expired(&self) -> bool;
    fn execute(&self) -> Self::Output;
    fn void(&self) -> Self::Output;

    fn is_valid(&self) -> bool { ... }
}

A Contract is a structure that can be invalidated or expired, on expiration the execute method is called, depending on the contract it could produce a value or not. If the contract is not valid at the time of the check it will be voided and could produce a value depending on the contract. Contracts are valid futures that can be run to completion on a reactor or awaited in an async block.

Required methods

fn is_expired(&self) -> bool

Check wether the contract has expired.

fn execute(&self) -> Self::Output

Produce a status of the contract on expiration.

fn void(&self) -> Self::Output

Produce a status of the contract on cancel.
