Trait StateHandling 

pub trait StateHandling {
    // Required methods
    fn state_type(&self) -> StateType;
    fn as_any(&self) -> &dyn Any;
    fn compare(&self, other: &dyn StateHandling) -> StateComparisonReport;

    // Provided method
    fn is_comparable(&self, other: &dyn StateHandling) -> bool { ... }
}

An interface to handle and compare the state of various types.

Required Methods

fn state_type(&self) -> StateType

Returns the StateType of the implementation.

fn as_any(&self) -> &dyn Any

Returns self as an Any.

fn compare(&self, other: &dyn StateHandling) -> StateComparisonReport

Compares this and another StateHandling implementation.

Notes

An implementation is expected to return

• an Error if the facilities of a backend cannot be used
• a StateComparisonReport::Incompatible if self and other are not compatible (see StateHandling::is_comparable)

Provided Methods

fn is_comparable(&self, other: &dyn StateHandling) -> bool

Checks whether this StateHandling implementation is comparable to another.

Returns true, if the StateType of self and that of other can be compared, false otherwise.

Note

It should not be necessary to specifically implement this method.
