Expand description

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§

Source

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

Returns a future that resolves when the connection is closed.

Source

fn connection_type(&self) -> ConnectionBackendType

Returns the type of the connection backend.

Source

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.

Source

fn is_closed(&self) -> bool

Returns true if the connection is currently closed.

Source

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.

Dyn Compatibility§

This trait is dyn compatible.

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