Service Capabilities indicate possible services that can be provided by each stream endpoint. See AVDTP Spec section 8.21.

Variants

MediaTransport

Indicates that the end point can provide at least basic media transport service as defined by RFC 3550 and outlined in section 7.2. Defined in section 8.21.2

Reporting

Indicates that the end point can provide reporting service as outlined in section 7.3 Defined in section 8.21.3

Recovery

Indicates the end point can provide recovery service as outlined in section 7.4 Defined in section 8.21.4

Fields

recovery_type: u8

max_recovery_window_size: u8

max_number_media_packets: u8

MediaCodec

Indicates the codec which is supported by this end point. |codec_extra| is defined within the relevant profiles (A2DP for Audio, etc). Defined in section 8.21.5

Fields

media_type: MediaType

codec_type: MediaCodecType

codec_extra: Vec<u8>

ContentProtection

Present when the device has content protection capability. |extra| is defined elsewhere. Defined in section 8.21.6

Fields

protection_type: ContentProtectionType

extra: Vec<u8>

HeaderCompression

Indicates that header compression capabilities is offered by this end point. Defined in section 8.21.7 TODO(https://fxbug.dev/42114013): Implement header compression specific fields to use the payload.

Fields

payload_len: u8

Multiplexing

Indicates that multiplexing service is offered by this end point. Defined in section 8.21.8 TODO(https://fxbug.dev/42114015): Implement multiplexing specific fields to use the payload.

Fields

payload_len: u8

DelayReporting

Indicates that delay reporting is offered by this end point. Defined in section 8.21.9

Implementations

impl ServiceCapability

pub fn category(&self) -> ServiceCategory

pub fn is_codec(&self) -> bool

pub fn codec_type(&self) -> Option<&MediaCodecType>

Trait Implementations

impl Clone for ServiceCapability

fn clone(&self) -> ServiceCapability

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ServiceCapability

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

Formats the value using the given formatter.

impl Decodable for ServiceCapability

type Error = Error

fn decode(from: &[u8]) -> Result<Self>

Decodes into a new object, or returns an error.

impl Encodable for ServiceCapability

type Error = Error

fn encoded_len(&self) -> usize

Returns the number of bytes necessary to encode |self|.

fn encode(&self, buf: &mut [u8]) -> Result<()>

Writes the encoded version of |self| at the start of |buf|. |buf| must be at least |self.encoded_len()| length.

impl PartialEq for ServiceCapability

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

Tests for self and other values to be equal, and is used by ==.

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

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