Struct DispatchResult 

pub struct DispatchResult { /* private fields */ }

Outcome of an event dispatch.

Carries the per-listener error list and aggregate counts. The internal representation is lazy: a DispatchResult for a fully successful dispatch holds an empty Vec (zero heap allocation — Vec::new does not allocate until first push). Allocation only happens when at least one listener returns Err or panics, keeping the success path allocation-free.

Implementations

impl DispatchResult

pub fn is_blocked(&self) -> bool

Whether the dispatch was halted by middleware.

pub fn listener_count(&self) -> usize

Total number of listeners invoked (successes + failures). Returns 0 when the dispatch was blocked.

pub fn success_count(&self) -> usize

Number of listeners that returned Ok(()) (or completed without panicking).

pub fn error_count(&self) -> usize

Number of listeners that returned Err(_) or panicked. A panicking listener contributes one error with the message prefix "listener panicked: ".

pub fn errors(&self) -> &[ListenerError]

Borrow every error produced by failing listeners, in dispatch order.

pub fn all_succeeded(&self) -> bool

true iff the dispatch was not blocked and every listener returned Ok(()).

pub fn has_errors(&self) -> bool

true iff at least one listener returned Err(_) or panicked.

Trait Implementations

impl Debug for DispatchResult

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
