Struct HandoffAttachment 

pub struct HandoffAttachment { /* private fields */ }

Opaque platform attachment created while transferring an accepted IPC connection to a backend process.

On Windows this owns the handle-table value that must be carried by the caller’s existing protocol. On Unix the descriptor travels out-of-band via SCM_RIGHTS. Native handle and descriptor values never cross the facade.

Implementations

impl HandoffAttachment

pub fn append_unsigned_varint(self, output: &mut Vec<u8>)

Append this attachment’s opaque value as an unsigned protobuf varint.

The caller owns the wire envelope while this facade retains ownership of the native value and its representation.

pub fn backend_may_adopt_before_offer(self) -> bool

Whether the backend may adopt the connection before its offer arrives.

Unix transfers the descriptor and token together in the sideband message, while Windows requires the later offer to identify the duplicated handle. Callers use this transport fact to make their own proxy-fallback ownership decision without selecting a host.
