Enum Payload 

#[repr(u8)]
pub enum Payload<'payload> {
    Outgoing {
        ptr: PtrConst,
        shape: &'static Shape,
        _lt: PhantomData<&'payload ()>,
    },
    Incoming(&'payload [u8]),
}

A payload — arguments for a request, or return type for a response.

Uses #[facet(opaque = PayloadAdapter)] so that format crates handle serialization/deserialization through the adapter contract:

• Send path: serialize_map extracts (ptr, shape) from Borrowed or Owned.
• Recv path: deserialize_build produces RawBorrowed or RawOwned.

Variants

Outgoing

Outgoing: type-erased pointer to caller-owned memory + its Shape.

Fields

ptr: PtrConst

shape: &'static Shape

_lt: PhantomData<&'payload ()>

Incoming(&'payload [u8])

Incoming: raw bytes borrowed from the backing (zero-copy).

Implementations

impl<'payload> Payload<'payload>

pub fn outgoing<T: Facet<'payload>>(value: &'payload T) -> Self

Construct an outgoing borrowed payload from a concrete value.

pub unsafe fn outgoing_unchecked(ptr: PtrConst, shape: &'static Shape) -> Self

Construct an outgoing owned payload from a raw pointer + shape.

Safety

The pointed value must remain alive until serialization has completed.

Trait Implementations

impl<'payload> Debug for Payload<'payload>

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

Formats the value using the given formatter.

impl<'payload, 'ʄ> Facet<'ʄ> for Payload<'payload>

where 'payload: 'ʄ, 'ʄ: 'payload,

const SHAPE: &'static Shape

The shape of this type, including: whether it’s a Struct, an Enum, something else?
