Enum SequenceFlags

#[repr(i32)]
pub enum SequenceFlags {
    SeqUnspecified = 0,
    SeqIncrementalStateCleared = 1,
    SeqNeedsIncrementalState = 2,
}

Variants

SeqUnspecified = 0

SeqIncrementalStateCleared = 1

Set by the writer to indicate that it will re-emit any incremental data for the packet’s sequence before referring to it again. This includes interned data as well as periodically emitted data like Process/ThreadDescriptors. This flag only affects the current packet sequence (see |trusted_packet_sequence_id|).

When set, this TracePacket and subsequent TracePackets on the same sequence will not refer to any incremental data emitted before this TracePacket. For example, previously emitted interned data will be re-emitted if it is referred to again.

When the reader detects packet loss (|previous_packet_dropped|), it needs to skip packets in the sequence until the next one with this flag set, to ensure intact incremental data.

SeqNeedsIncrementalState = 2

This packet requires incremental state, such as TracePacketDefaults or InternedData, to be parsed correctly. The trace reader should skip this packet if incremental state is not valid on this sequence, i.e. if no packet with the SEQ_INCREMENTAL_STATE_CLEARED flag has been seen on the current |trusted_packet_sequence_id|.

Implementations

impl SequenceFlags

pub fn is_valid(value: i32) -> bool

Returns true if value is a variant of SequenceFlags.

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

👎Deprecated: Use the TryFrom<i32> implementation instead

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

impl SequenceFlags

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 SequenceFlags

fn clone(&self) -> SequenceFlags

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for SequenceFlags

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

Formats the value using the given formatter.

impl Default for SequenceFlags

fn default() -> SequenceFlags

Returns the “default value” for a type.

impl From<SequenceFlags> for i32

fn from(value: SequenceFlags) -> i32

Converts to this type from the input type.

impl Hash for SequenceFlags

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 SequenceFlags

fn cmp(&self, other: &SequenceFlags) -> 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 SequenceFlags

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

fn partial_cmp(&self, other: &SequenceFlags) -> 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 SequenceFlags

type Error = DecodeError

The type returned in the event of a conversion error.

fn try_from(value: i32) -> Result<SequenceFlags, DecodeError>

Performs the conversion.
