Struct ChannelParameters

pub struct ChannelParameters {
    pub channel_mode: Option<ChannelMode>,
    pub max_rx_packet_size: Option<u16>,
    pub security_requirements: Option<SecurityRequirements>,
    pub flush_timeout: Option<i64>,
    /* private fields */
}

The set of parameters to use or that were used to establish an L2CAP connection-oriented channel.

Fields

channel_mode: Option<ChannelMode>

Optional. For BR/EDR: If not provided, BASIC will be used. For LE: If not provided, LE_CREDIT_BASED_FLOW_CONTROL will be used.

max_rx_packet_size: Option<u16>

Maximum packet size this profile is capable of accepting. Must be >= 48. Optional. If not provided, the size will be determined by the Bluetooth system. No guarantees are given regarding the size selected.

security_requirements: Option<SecurityRequirements>

For BR/EDR: Minimum security requirements a link must have before this channel can be created. The requirements provided here will be attempted with the peer before the channel is established. If a peer cannot provide the requirements, the channel is closed. Optional. If not provided, then the only security property guaranteed is encryption.

For LE: Unused, must not be present.

flush_timeout: Option<i64>

For BR/EDR: The flush timeout indicates the maximum amount of time a data packet should be buffered in the controller before it is dropped. A flush timeout of infinity can be used to mark packets as flushable without any particular flush timeout. Range: 1ms - 1,279ms (or ∞). Rounded down. Optional. If not provided, no flush timeout and packets are not flushable.

For LE: Unused, must not be present.

Trait Implementations

impl Clone for ChannelParameters

fn clone(&self) -> ChannelParameters

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ChannelParameters

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

Formats the value using the given formatter.

impl<D: ResourceDialect> Decode<ChannelParameters, D> for ChannelParameters

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<'_, D>, offset: usize, depth: Depth, ) -> Result<()>

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

impl Default for ChannelParameters

fn default() -> ChannelParameters

Returns the “default value” for a type.

impl<D: ResourceDialect> Encode<ChannelParameters, D> for &ChannelParameters

unsafe fn encode( self, encoder: &mut Encoder<'_, D>, 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 ChannelParameters

fn eq(&self, other: &ChannelParameters) -> 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 TypeMarker for ChannelParameters

type Owned = ChannelParameters

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.

impl ValueTypeMarker for ChannelParameters

type Borrowed<'a> = &'a ChannelParameters

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

fn borrow(value: &<Self as TypeMarker>::Owned) -> Self::Borrowed<'_>

Cheaply converts from &Self::Owned to Self::Borrowed.
