Trait Connection 

pub trait Connection:
    Stream<Item = Result<Vec<u8>, Status>>
    + Sink<Vec<u8>, Error = Status>
    + Send
    + Sync
    + Debug
    + Unpin {
    // Required methods
    fn closed<'a>(
        &'a self,
    ) -> Pin<Box<dyn Future<Output = Result<(), Status>> + 'a>>;
    fn connection_type(&self) -> ConnectionBackendType;
    fn write(&self, bytes: &[u8]) -> Result<usize, Status>;
    fn is_closed(&self) -> bool;
    fn into_fidl_channel(self: Box<Self>) -> Result<Channel, Status>;
}

A trait representing a Bluetooth data connection. Concrete implementations handle the specific transport mechanism (e.g., socket or FIDL protocol) while fulfilling the Sink and Stream contracts for data transfer.

Required Methods

fn closed<'a>( &'a self, ) -> Pin<Box<dyn Future<Output = Result<(), Status>> + 'a>>

Returns a future that resolves when the connection is closed.

fn connection_type(&self) -> ConnectionBackendType

Returns the type of the connection backend.

fn write(&self, bytes: &[u8]) -> Result<usize, Status>

Writes data to the connection. This is a non-blocking fast path. Returns SHOULD_WAIT if the buffer is full.

fn is_closed(&self) -> bool

Returns true if the connection is currently closed.

fn into_fidl_channel(self: Box<Self>) -> Result<Channel, Status>

Consumes the connection and returns a partially filled FIDL channel containing the transport (e.g., socket handle) if applicable.
