Enum JoinTrigger 

pub enum JoinTrigger {
    Input {
        index: usize,
        value: Box<dyn Any + Send>,
    },
}

Tells the join handler which input produced a value.

Users match on the index (corresponding to .input() call order) and downcast to recover the typed value.

Variants

Input

An input at the given index fired with a type-erased value.

Fields

index: usize

value: Box<dyn Any + Send>

Implementations

impl JoinTrigger

pub fn as_input<T: 'static>(&self) -> Option<&T>

Convenience: try to downcast the trigger value as the expected input type.

pub fn index(&self) -> usize

Returns the input index that triggered this event.
