Enum linux_perf_event_reader::IpSkidConstraint

pub enum IpSkidConstraint {
    ArbitrarySkid,
    ConstantSkid,
    ZeroSkid,
    ZeroSkidOrRandomization,
}

Specifies how precise the instruction address should be. With perf record -e you can set the precision by appending /p to the event name, with varying numbers of ps.

Variants

ArbitrarySkid

0 - SAMPLE_IP can have arbitrary skid

ConstantSkid

1 - SAMPLE_IP must have constant skid

ZeroSkid

2 - SAMPLE_IP requested to have 0 skid

ZeroSkidOrRandomization

3 - SAMPLE_IP must have 0 skid, or uses randomization to avoid sample shadowing effects.

Trait Implementations

impl Clone for IpSkidConstraint

fn clone(&self) -> IpSkidConstraint

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for IpSkidConstraint

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

Formats the value using the given formatter.

impl Hash for IpSkidConstraint

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 IpSkidConstraint

fn cmp(&self, other: &IpSkidConstraint) -> 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 + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for IpSkidConstraint

fn eq(&self, other: &IpSkidConstraint) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for IpSkidConstraint

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

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

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

This method tests less than (for self and other) and is used by the < operator.

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

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

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

This method tests greater than (for self and other) and is used by the > operator.

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

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