Struct component_events::sequence::EventGroup

pub struct EventGroup { /* private fields */ }

Implementations

impl EventGroup

pub fn new( events: Vec<EventMatcher>, ordering: Ordering, contains: Contains ) -> Self

pub fn is_empty(&self) -> bool

pub fn event_names(&self) -> Result<Vec<String>, Error>

pub fn next(&mut self, event: &EventDescriptor) -> Result<bool, Error>

Returns true if event matches an event matcher in this group.

If the group ordering is Ordered, the event must match the first matcher. If the group ordering is Unordered, the event can match any matcher in the group. The matcher is removed after a successful match.

Returns an error if the event does not match a matcher and the contains policy is All, indicating that the unknown event did not match the group.

Returns Ok(true) if there is a positive match. Returns Ok(false) if the EventGroup is empty.
