Struct AppendFrameOutcome 

pub struct AppendFrameOutcome {
    pub stream_id: String,
    pub frame_count: u64,
}

Outcome of append_frame().

RFC-012 §R7.2.1: canonical definition moved to ff_core::backend::AppendFrameOutcome; this pub use shim preserves the ff_sdk::task::AppendFrameOutcome path through the 0.4.x window. Existing consumers construct + match exhaustively without change. The derive set widened from Clone, Debug to Clone, Debug, PartialEq, Eq matching the FailOutcome precedent. Outcome of an append_frame() call.

RFC-012 §R7.2.1: moved from ff_sdk::task::AppendFrameOutcome to ff_core::backend::AppendFrameOutcome so it is nameable by the EngineBackend::append_frame trait return. ff_sdk::task retains a pub use shim preserving the ff_sdk::task::AppendFrameOutcome path through 0.4.x.

Derive set matches the FailOutcome precedent (Clone, Debug, PartialEq, Eq). Not #[non_exhaustive]: construction is internal to the backend today (parser in ff-backend-valkey), and no external constructors are anticipated (consumer-shape evidence per §R7.2.1 / MN3).

stream_id: String is a stable shape commitment — a future typed StreamId newtype would be its own breaking change (§R7.5.6 / MD2).

Fields

stream_id: String

Valkey Stream entry ID assigned to this frame (e.g. 1234567890-0).

frame_count: u64

Total frame count in the stream after this append.

Trait Implementations

impl Clone for AppendFrameOutcome

fn clone(&self) -> AppendFrameOutcome

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AppendFrameOutcome

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

Formats the value using the given formatter.

impl PartialEq for AppendFrameOutcome

fn eq(&self, other: &AppendFrameOutcome) -> 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.
