Struct DeciderTestSpecification

Source 
pub struct DeciderTestSpecification<'a, Command, State, Event, Error>
where
    Event: PartialEq + Debug,
    Error: PartialEq + Debug,
{ /* private fields */ }
Expand description

A test specification DSL for deciders that supports the given-when-then format. The DSL is used to specify the events that have already occurred (GIVEN), the command that is being executed (WHEN), and the expected events (THEN) that should be generated.

fn fg(&self, value: Color) -> Painted<&T>

painted.fg(Color::White);

Source§

fn quirk(&self, value: Quirk) -> Painted<&T>
