Enum FerroBody 

pub enum FerroBody {
    Full(Full<Bytes>),
    Stream(SseStream),
}

Unified HTTP response body for the framework’s hyper serve loop.

Carries either a fully-buffered body (Full<Bytes>) or a streaming SSE body (SseStream), allowing the same hyper::Response<FerroBody> type to flow through all response-path code without dynamic dispatch or heap allocation on the buffered hot path.

Structural compression rule (D-06)

If a compression layer is added in a future phase it MUST match on FerroBody::Full only and pass FerroBody::Stream through untouched. A streaming body cannot be whole-body buffered without breaking the SSE protocol.

Error type

FerroBody::Error = Infallible — both variants are infallible so the serve loop’s Ok::<_, Infallible>(...) wrapper is unchanged.

Variants

Full(Full<Bytes>)

Fully-buffered response body (the common, allocation-free path).

Stream(SseStream)

Streaming SSE body (held-open connection; yields frames as events arrive).

Implementations

impl FerroBody

pub fn is_streaming(&self) -> bool

Returns true if this body is the streaming Stream variant.

Structural compression rule (D-06)

If a compression layer is added in a future phase, it must check is_streaming() and pass FerroBody::Stream bodies through untouched — only FerroBody::Full can be whole-body buffered without breaking the SSE protocol.

Trait Implementations
