Enum DataLossReason 

#[repr(i32)]
pub enum DataLossReason {
    DataLossUnspecified = 0,
    DataLossPresent = 1,
    DataLossReadGap = 2,
    DataLossChunkCorrupted = 4,
    DataLossOrphanContinuation = 8,
    DataLossReassemblyGap = 16,
    DataLossReassemblyBrokenChain = 32,
    DataLossOverwrite = 64,
    DataLossWriterAbort = 128,
    DataLossSmbFull = 256,
}

Bit flags OR-ed together into |previous_packet_dropped| to describe why packets were dropped. DATA_LOSS_PRESENT is set on every loss; the remaining bits attribute the cause and are set either by TraceBufferV2 in the service or by the producer’s trace writer.

Variants

DataLossUnspecified = 0

DataLossPresent = 1

A loss was detected (set on every loss). On its own (value 1) it means dropped with no specific cause, e.g. TraceBufferV1 or a producer.

DataLossReadGap = 2

A read started on a non-successor ChunkID (a gap in the stream).

DataLossChunkCorrupted = 4

A chunk’s fragments couldn’t be tokenized (malformed / out-of-bounds).

DataLossOrphanContinuation = 8

A continuation/end fragment with no preceding begin fragment.

DataLossReassemblyGap = 16

Reassembly abandoned because of a ChunkID gap mid-packet.

DataLossReassemblyBrokenChain = 32

Reassembly abandoned because the fragment chain was broken even though the ChunkIDs were contiguous.

DataLossOverwrite = 64

Unconsumed fragments were evicted while overwriting (ring buffer wrap).

DataLossWriterAbort = 128

The trace writer aborted an in-progress fragmented packet (it stamped the kPacketSizeDropPacket sentinel in the last fragment header).

DataLossSmbFull = 256

The producer’s shared memory buffer was full: the trace writer couldn’t acquire a chunk and dropped packets until one became available. Set by the producer, not the service.

Implementations

impl DataLossReason

pub const fn is_valid(value: i32) -> bool

Returns true if value is a variant of DataLossReason.

pub fn from_i32(value: i32) -> Option<DataLossReason>

👎Deprecated:

Use the TryFrom<i32> implementation instead

Converts an i32 to a DataLossReason, or None if value is not a valid variant.

impl DataLossReason

pub fn as_str_name(&self) -> &'static str

String value of the enum field names used in the ProtoBuf definition.

The values are not transformed in any way and thus are considered stable (if the ProtoBuf definition does not change) and safe for programmatic use.

pub fn from_str_name(value: &str) -> Option<Self>

Creates an enum from field names used in the ProtoBuf definition.

Trait Implementations

impl Clone for DataLossReason

fn clone(&self) -> DataLossReason

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DataLossReason

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

Formats the value using the given formatter.

impl Default for DataLossReason

fn default() -> DataLossReason

Returns the “default value” for a type.

impl From<DataLossReason> for i32

fn from(value: DataLossReason) -> i32

Converts to this type from the input type.

impl Hash for DataLossReason

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for DataLossReason

fn cmp(&self, other: &DataLossReason) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for DataLossReason

fn eq(&self, other: &DataLossReason) -> 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 PartialOrd for DataLossReason

fn partial_cmp(&self, other: &DataLossReason) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl TryFrom<i32> for DataLossReason

type Error = UnknownEnumValue

The type returned in the event of a conversion error.

fn try_from(value: i32) -> Result<DataLossReason, UnknownEnumValue>

Performs the conversion.
