TCP protocol state.

Fields

state: Option<State>

The current state of the TCP state machine.

ca_state: Option<CongestionControlState>

The current state of the TCP congention avoidance state machine.

rto_usec: Option<u32>

The current RTO value in microseconds.

tcpi_last_data_sent_msec: Option<u32>

Time since data was last sent on the connection in milliseconds.

tcpi_last_ack_recv_msec: Option<u32>

Time since the most recent ACK was received in milliseconds.

rtt_usec: Option<u32>

The estimated smoothed roundtrip time in microseconds.

rtt_var_usec: Option<u32>

The smoothed mean deviation of the roundtrip time in microseconds.

snd_ssthresh: Option<u32>

The sending slow start threshold in segments.

snd_cwnd: Option<u32>

tcpi_total_retrans: Option<u32>

The total number of retransmission events.

tcpi_segs_out: Option<u64>

Trait Implementations

impl Clone for Info

fn clone(&self) -> Info

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Info

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

Formats the value using the given formatter.

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

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 Info

fn default() -> Info

Returns the “default value” for a type.

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

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 Info

fn eq(&self, other: &Info) -> 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 Info

type Owned = Info

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 Info

type Borrowed<'a> = &'a Info

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.

impl Persistable for Info
