Struct FrameCodecFactory 

pub struct FrameCodecFactory(/* private fields */);

Makes the FrameCodec instances for one sink: one per chain. Cloning shares the factory.

The closure is RefUnwindSafe, so the factory, and a sink type that holds one, stays UnwindSafe and RefUnwindSafe.

A closure that captures state which is not RefUnwindSafe wraps it in AssertUnwindSafe and reaches it through deref, as in let state: &T = &wrapper;. From edition 2021 a closure that names wrapper.0 captures only the inner field, which loses the wrapper and fails the bound.

Implementations

impl FrameCodecFactory

pub fn new( make: impl Fn() -> Box<dyn FrameCodec> + Send + Sync + RefUnwindSafe + 'static, ) -> Self

Wrap make, which builds one codec instance per call.

pub fn make(&self) -> Box<dyn FrameCodec>

Build a fresh codec instance.
