Trait issue_states::condition::Condition

pub trait Condition {
    type Issue;

    fn satisfied_by(&self, issue: &Self::Issue) -> bool;
}

Trait for issue metadata conditions

A Condition represents a predicate for an issue state: a function mapping an issue to a boolean value indicating whether the condition is fulfilled or not. It is generally assumed that a condition consists of “condition atoms”, which each specify a “singular” condition on a specific piece of metadata.

Whatever is used as type for conditions on metadata has to implement this trait. It enables IssueStates to evaluate the condition. Additionally, the ConditionFactory trait should be implemented in order to enable parsing conditions from configuration files.

Required Associated Types

type Issue

Type of the issue being evaluated

Alternatively, some representation of the metadata may be used in place of the issue type.

Required Methods

fn satisfied_by(&self, issue: &Self::Issue) -> bool

Check whether the condition is satisfied by the issue provided
