Struct bt_rfcomm::DLCI

source ·
pub struct DLCI(/* private fields */);
Expand description

Identifier for a direct link connection (DLC) between devices.

Use the provided u8::try_from implementation to construct a valid DLCI.

The DLCI is 6 bits wide and is split into a direction bit and a 5-bit Server Channel number. DLCIs 1 and 62-63 are reserved and never used in RFCOMM. See RFCOMM 5.4.

Implementations§

source§

impl DLCI

source

pub const MUX_CONTROL_DLCI: DLCI = _

The control channel for the RFCOMM Multiplexer.

source

pub fn is_mux_control(&self) -> bool

source

pub fn is_user(&self) -> bool

source

pub fn validate(&self, role: Role) -> Result<(), RfcommError>

Returns Ok(()) if the DLCI belongs to the side of the session with the given role - this is only applicable to User DLCIs.

The DLCI space is divided into two equal parts. RFCOMM 5.2 states: “…this partitions the DLCI value space such that server applications on the non- initiating device are reachable on DLCIs 2,4,6,…,60, and server applications on the initiating device are reachable on DLCIs 3,5,7,…,61.”

source

pub fn initiator(&self, role: Role) -> Result<bool, RfcommError>

Returns true if the DLCI is initiated by this device. Returns an Error if the provided role is invalid or if the DLCI is not a user DLCI.
