Struct rubble::l2cap::BleChannelMap

pub struct BleChannelMap<A: AttributeProvider, S: SecurityLevel> {
    att: AttributeServer<A>,
    signaling: SignalingState,
    sm: SecurityManager<S>,
}

A fixed BLE channel map that provides only the required channel endpoints and does not allow dynamic channels.

The channels are mapped as follows (no other channels are supported):

• 0x0004: Attribute protocol (ATT).
• 0x0005: LE L2CAP signaling channel.
• 0x0006: LE Security Manager protocol.

Fields

att: AttributeServer<A>

signaling: SignalingState

sm: SecurityManager<S>

Implementations

impl BleChannelMap<NoAttributes, NoSecurity>

pub fn empty() -> Self

Creates a new channel map with no backing data for the connected protocols.

This means:

• The attribute server on channel 0x0004 will host an empty attribute set.
• The security manager on channel 0x0006 will not support pairing or any security.

impl<A: AttributeProvider> BleChannelMap<A, NoSecurity>

pub fn with_attributes(att: A) -> Self

pub fn attribute_provider(&mut self) -> &mut A

Provides mutable access to the underlying AttributeProvider.

Trait Implementations

impl<A: AttributeProvider, S: SecurityLevel> ChannelMapper for BleChannelMap<A, S>

type AttributeProvider = A

The attribute provider used by the ATT server.

fn lookup(
    &mut self,
    channel: Channel
) -> Option<ChannelData<'_, dyn ProtocolObj>>

Look up what’s connected to channel (eg. the Protocol to which to forward).

fn att(&mut self) -> ChannelData<'_, AttributeServer<Self::AttributeProvider>>

Returns information about the Attribute Protocol on channel 0x0004.
