Struct bt_rfcomm::DLCI

pub struct DLCI(_);

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

impl DLCI

pub const MUX_CONTROL_DLCI: DLCI = _

The control channel for the RFCOMM Multiplexer.

pub fn is_mux_control(&self) -> bool

pub fn is_user(&self) -> bool

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.”

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.

Trait Implementations

impl Clone for DLCI

fn clone(&self) -> DLCI

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for DLCI

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl From<DLCI> for u8

fn from(value: DLCI) -> u8

Converts to this type from the input type.

impl Hash for DLCI

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq<DLCI> for DLCI

fn eq(&self, other: &DLCI) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl TryFrom<DLCI> for ServerChannel

type Error = Error

The type returned in the event of a conversion error.

fn try_from(dlci: DLCI) -> Result<ServerChannel, Self::Error>

Performs the conversion.

impl TryFrom<u8> for DLCI

type Error = FrameParseError

The type returned in the event of a conversion error.

fn try_from(value: u8) -> Result<DLCI, Self::Error>

Performs the conversion.
