Trait DirectionMeta 

pub trait DirectionMeta: Sealed { }

Associates each direction marker with the metadata type it carries inside Request<R, D>.

This trait is sealed: only Outbound and Incoming implement it. Users cannot add new implementations.

The associated type DirectionMeta::Meta is an implementation detail and should not be used directly. Access server-injected metadata through the dedicated accessors on IncomingRequest instead:

• Request::istag — the ISTag resolved from ServiceOptions before the handler was called.
• Request::chunk_trailers — HTTP chunk trailer headers (RFC 7230 §4.1.2).

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
