Struct BeforeCallbackOutcome 

pub struct BeforeCallbackOutcome { /* private fields */ }

The outcome of one registration-order before-callback pass.

Implementations

impl BeforeCallbackOutcome

pub const fn entered(self) -> usize

Returns how many listeners completed their before callback.

The matching reverse pass runs exactly these listeners, so a listener that failed or never ran receives no completion callback.

pub const fn failure(self) -> Option<ItemListenerFailure>

Returns the first failure, when the pass stopped early.

pub const fn is_ok(self) -> bool

Returns whether every registered listener completed.

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.

impl PartialOrd for BeforeCallbackOutcome

fn partial_cmp(&self, other: &BeforeCallbackOutcome) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.
