Enum Interval 

pub enum Interval {
    Frequency(u64),
    Period(u64),
}

How often the per-cpu sampling will occur. Not guaranteed to be honored as the kernel can throttle the sampling rate if it’s too high. If unset, an implementation-defined default is used.

Variants

Frequency(u64)

Per-cpu sampling frequency in Hz, as requested from the kernel. Not the same as 1/period. Details: the actual sampling will still be based on a period, but the kernel will dynamically adjust it based on the observed event rate, to approximate this frequency. Works best with steady-rate events like timers.

Period(u64)

Per-cpu sampling will occur every |period| counts of |event|. Prefer |frequency| by default, as it’s easier to oversample with a fixed period.

Implementations

impl Interval

pub fn encode(&self, buf: &mut impl BufMut)

Encodes the message to a buffer.

pub fn merge( field: &mut Option<Interval>, tag: u32, wire_type: WireType, buf: &mut impl Buf, ctx: DecodeContext, ) -> Result<(), DecodeError>

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

pub fn encoded_len(&self) -> usize

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

Trait Implementations

impl Clone for Interval

fn clone(&self) -> Interval

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Interval

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

Formats the value using the given formatter.

impl PartialEq for Interval

fn eq(&self, other: &Interval) -> 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 Copy for Interval

impl StructuralPartialEq for Interval
