Enum EffectPayload 

pub enum EffectPayload<E> {
    Emitted {
        variant: EffectVariantId,
        body: E,
    },
}

Typed effect payload. Generic over the producer composition’s seam-effect sum (see the codegen-emitted {Composition}Effect enum).

The variant carries the typed EffectVariantId alongside the body so the dispatcher can look up a route without pattern-matching on the producer’s effect enum (the ProducerEffect trait hides that under ProducerEffect::variant_id).

Variants

Emitted

Producer emitted a typed effect variant.

Fields

variant: EffectVariantId

Typed variant id (matches the producer’s effect enum tag).

body: E

The typed effect body.

Implementations

impl<E: ProducerEffect> EffectPayload<E>

pub fn variant(&self) -> &EffectVariantId

Borrow the typed variant id.

pub fn body(&self) -> &E

Borrow the typed body.

Trait Implementations

impl<E: Clone> Clone for EffectPayload<E>

fn clone(&self) -> EffectPayload<E>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<E: Debug> Debug for EffectPayload<E>

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

Formats the value using the given formatter.

impl<E: PartialEq> PartialEq for EffectPayload<E>

fn eq(&self, other: &EffectPayload<E>) -> bool

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
