Struct FtraceKprobeStats

pub struct FtraceKprobeStats {
    pub hits: Option<i64>,
    pub misses: Option<i64>,
}

Kprobe statistical data, gathered from /sys/kernel/tracing/kprobe_profile.

Fields

hits: Option<i64>

Cumulative number of kprobe events generated for this function

misses: Option<i64>

Cumulative number of kprobe events that could not be generated for this function and were missed. This happens when too much nesting happens between a kprobe and its kretprobe, overflowing the maxactives buffer.

Implementations

impl FtraceKprobeStats

pub fn hits(&self) -> i64

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

pub fn misses(&self) -> i64

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

Trait Implementations

impl Clone for FtraceKprobeStats

fn clone(&self) -> FtraceKprobeStats

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for FtraceKprobeStats

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

Formats the value using the given formatter.

impl Default for FtraceKprobeStats

fn default() -> Self

Returns the “default value” for a type.

impl Message for FtraceKprobeStats

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<B>(&self, buf: &mut B) -> Result<(), EncodeError>

where B: BufMut, 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<B>(&self, buf: &mut B) -> Result<(), EncodeError>

where B: BufMut, 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<B>(buf: B) -> Result<Self, DecodeError>

where B: Buf, Self: Default,

Decodes an instance of the message from a buffer.

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

where B: Buf, Self: Default,

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

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

where B: Buf, Self: Sized,

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

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

where B: Buf, Self: Sized,

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

impl PartialEq for FtraceKprobeStats

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