Struct ShadowBufferStats 

pub struct ShadowBufferStats {
    pub packets_seen: Option<u64>,
    pub packets_in_both: Option<u64>,
    pub packets_only_v1: Option<u64>,
    pub packets_only_v2: Option<u64>,
    pub patches_attempted: Option<u64>,
    pub v1_patches_succeeded: Option<u64>,
    pub v2_patches_succeeded: Option<u64>,
    pub stats_version: Option<u32>,
}

Statistics for TRACE_BUFFER_V2_SHADOW_MODE comparison. Only populated when the buffer is configured with shadow mode.

Fields

packets_seen: Option<u64>

Total num. packets read. This is not affected by capping of the hasher to 32K elements.

packets_in_both: Option<u64>

Num. packets found in both V1 and V2 buffers (matched by content hash).

packets_only_v1: Option<u64>

Num. packets found only in V1 buffer but not in V2.

packets_only_v2: Option<u64>

Num. packets found only in V2 buffer but not in V1.

patches_attempted: Option<u64>

Num. patch operations attempted.

v1_patches_succeeded: Option<u64>

Num. patches that succeeded on V1 buffer.

v2_patches_succeeded: Option<u64>

Num. patches that succeeded on V2 buffer.

stats_version: Option<u32>

This is to distinguish the updated calculations after fixing the hashes. This field is either empty or “2”

pub fn packets_only_v2(&self) -> u64

Returns the value of packets_only_v2, or the default value if packets_only_v2 is unset.

pub fn patches_attempted(&self) -> u64

Returns the value of patches_attempted, or the default value if patches_attempted is unset.

pub fn v1_patches_succeeded(&self) -> u64

Returns the value of v1_patches_succeeded, or the default value if v1_patches_succeeded is unset.

pub fn v2_patches_succeeded(&self) -> u64

Returns the value of v2_patches_succeeded, or the default value if v2_patches_succeeded is unset.

pub fn stats_version(&self) -> u32

Returns the value of stats_version, or the default value if stats_version is unset.

Trait Implementations

impl Clone for ShadowBufferStats

fn clone(&self) -> ShadowBufferStats

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ShadowBufferStats

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

Formats the value using the given formatter.

impl Default for ShadowBufferStats

fn default() -> Self

Returns the “default value” for a type.

impl Hash for ShadowBufferStats

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 Message for ShadowBufferStats

fn encoded_len(&self) -> usize

Returns the encoded length of the message without a length delimiter.

fn clear(&mut self)

Clears the message, resetting all fields to their default.

fn encode(&self, buf: &mut impl BufMut) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message to a buffer.

fn encode_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message to a newly allocated buffer.

fn encode_length_delimited( &self, buf: &mut impl BufMut, ) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message with a length-delimiter to a buffer.

fn encode_length_delimited_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message with a length-delimiter to a newly allocated buffer.

fn decode(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes an instance of the message from a buffer.

fn decode_length_delimited(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes a length-delimited instance of the message from the buffer.

fn merge(&mut self, buf: impl Buf) -> Result<(), DecodeError>

where Self: Sized,

Decodes an instance of the message from a buffer, and merges it into self.

fn merge_length_delimited(&mut self, buf: impl Buf) -> Result<(), DecodeError>

where Self: Sized,

Decodes a length-delimited instance of the message from buffer, and merges it into self.

impl PartialEq for ShadowBufferStats

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