Struct Channel

pub struct Channel {
    pub socket: Option<Socket>,
    pub channel_mode: Option<ChannelMode>,
    pub max_tx_sdu_size: Option<u16>,
    pub ext_direction: Option<ClientEnd<AudioDirectionExtMarker>>,

}

A channel opened to a peer.

Fields

socket: Option<Socket>

Deprecated. Socket interface for sending/receiving SDUs on the channel. The channel will be closed if both this socket and the Connection are closed. Always present.

channel_mode: Option<ChannelMode>

Channel mode accepted by the peer. Always present.

max_tx_sdu_size: Option<u16>

Maximum SDU size the peer is capable of accepting. Always present.

ext_direction: Option<ClientEnd<AudioDirectionExtMarker>>

Audio Direction priority extension. See AudioDirectionExt. Present only if supported.

flush_timeout: Option<i64>

ext_l2cap: Option<ClientEnd<L2capParametersExtMarker>>

L2CAP parameter extension. See L2capParametersExt. Always present for L2CAP Channels, never present for other Channels.

ext_audio_offload: Option<ClientEnd<AudioOffloadExtMarker>>

Audio offload extension. See AudioOffloadExt. Present only if supported.

connection: Option<ClientEnd<ChannelMarker>>

Protocol for sending/receiving SDUs on the channel. If present, closing this and socket will close the channel.

Trait Implementations

impl Debug for Channel

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

Formats the value using the given formatter.

impl Decode<Channel, DefaultFuchsiaResourceDialect> for Channel

fn new_empty() -> Self

Creates a valid instance of Self. The specific value does not matter, since it will be overwritten by decode.

unsafe fn decode( &mut self, decoder: &mut Decoder<'_, DefaultFuchsiaResourceDialect>, offset: usize, depth: Depth, ) -> Result<()>

Decodes an object of type T from the decoder’s buffers into self.

impl Default for Channel

fn default() -> Channel

Returns the “default value” for a type.

impl Encode<Channel, DefaultFuchsiaResourceDialect> for &mut Channel

unsafe fn encode( self, encoder: &mut Encoder<'_, DefaultFuchsiaResourceDialect>, offset: usize, depth: Depth, ) -> Result<()>

Encodes the object into the encoder’s buffers. Any handles stored in the object are swapped for Handle::INVALID.

impl PartialEq for Channel

fn eq(&self, other: &Channel) -> 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.

impl ResourceTypeMarker for Channel

type Borrowed<'a> = &'a mut Channel

The Rust type to use for encoding. This is a particular Encode<Self> type cheaply obtainable from &mut Self::Owned. There are three cases:

fn take_or_borrow<'a>( value: &'a mut <Self as TypeMarker>::Owned, ) -> Self::Borrowed<'a>

Cheaply converts from &mut Self::Owned to Self::Borrowed. For HandleBased types this is “take” (it returns an owned handle and replaces value with Handle::invalid), and for all other types it is “borrow” (just converts from one reference to another).

impl TypeMarker for Channel

type Owned = Channel

The owned Rust type which this FIDL type decodes into.

fn inline_align(_context: Context) -> usize

Returns the minimum required alignment of the inline portion of the encoded object. It must be a (nonzero) power of two.

fn inline_size(_context: Context) -> usize

Returns the size of the inline portion of the encoded object, including padding for alignment. Must be a multiple of inline_align.

fn encode_is_copy() -> bool

Returns true if the memory layout of Self::Owned matches the FIDL wire format and encoding requires no validation. When true, we can optimize encoding arrays and vectors of Self::Owned to a single memcpy.

fn decode_is_copy() -> bool

Returns true if the memory layout of Self::Owned matches the FIDL wire format and decoding requires no validation. When true, we can optimize decoding arrays and vectors of Self::Owned to a single memcpy.
