Struct Chain 

pub struct Chain<A, B>(pub A, pub B);

Compose two transforms into one, running A then B on its output, so a static chain can carry more than one middle stage without a heap-allocated element list: Chain(a, Chain(b, c)) is a three-transform pipeline that still monomorphizes to one unboxed future. A dropping a frame (Ok(None)) short-circuits B.

Tuple Fields

0: A

1: B

Trait Implementations

impl<A: Debug, B: Debug> Debug for Chain<A, B>

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

Formats the value using the given formatter.

impl<A: Recover, B: Recover> Recover for Chain<A, B>

async fn recover(&mut self) -> Result<(), G2gError>

Re-initialize after a fault. The default is a no-op (a stateless stage).

impl<A: StaticTransform, B: StaticTransform> StaticTransform for Chain<A, B>

async fn process(&mut self, input: Frame) -> Result<Option<Frame>, G2gError>

Transform input, optionally producing an output frame.
