Enum KsymsMemPolicy

#[repr(i32)]
pub enum KsymsMemPolicy {
    KsymsUnspecified = 0,
    KsymsCleanupOnStop = 1,
    KsymsRetain = 2,
}

When symbolize_ksyms=true, determines whether the traced_probes daemon should keep the symbol map in memory (and reuse it for future tracing sessions) or clear it (saving memory) and re-create it on each tracing session (wasting cpu and wall time). The tradeoff is roughly: KSYMS_RETAIN: pay a fixed ~1.2 MB cost after the first trace. KSYMS_CLEANUP_ON_STOP: pay a ~300-500ms cost when starting each trace. Default behavior: KSYMS_CLEANUP_ON_STOP.

Variants

KsymsUnspecified = 0

KsymsCleanupOnStop = 1

KsymsRetain = 2

Implementations

impl KsymsMemPolicy

pub fn is_valid(value: i32) -> bool

Returns true if value is a variant of KsymsMemPolicy.

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

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

impl KsymsMemPolicy

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.

Trait Implementations

impl Clone for KsymsMemPolicy

fn clone(&self) -> KsymsMemPolicy

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for KsymsMemPolicy

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

Formats the value using the given formatter.

impl Default for KsymsMemPolicy

fn default() -> KsymsMemPolicy

Returns the “default value” for a type.

impl From<KsymsMemPolicy> for i32

fn from(value: KsymsMemPolicy) -> i32

Converts to this type from the input type.

impl Hash for KsymsMemPolicy

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 KsymsMemPolicy

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

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

fn partial_cmp(&self, other: &KsymsMemPolicy) -> 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.
