Struct LinuxMemory 

pub struct LinuxMemory { /* private fields */ }

LinuxMemory for Linux cgroup ‘memory’ resource management.

Implementations

impl LinuxMemory

pub fn limit(&self) -> Option<i64>

Memory limit (in bytes).

pub fn reservation(&self) -> Option<i64>

Memory reservation or soft_limit (in bytes).

pub fn swap(&self) -> Option<i64>

Total memory limit (memory + swap).

pub fn kernel(&self) -> Option<i64>

Kernel memory limit (in bytes).

Deprecated

kernel-memory limits are not supported in cgroups v2, and were obsoleted in kernel v5.4.

pub fn kernel_tcp(&self) -> Option<i64>

Kernel memory limit for tcp (in bytes).

pub fn swappiness(&self) -> Option<u64>

How aggressive the kernel will swap memory pages.

pub fn disable_oom_killer(&self) -> Option<bool>

DisableOOMKiller disables the OOM killer for out of memory conditions.

pub fn use_hierarchy(&self) -> Option<bool>

Enables hierarchical memory accounting

pub fn check_before_update(&self) -> Option<bool>

Enables checking if a new memory limit is lower

impl LinuxMemory

pub fn set_limit(&mut self, val: Option<i64>) -> &mut Self

Memory limit (in bytes).

pub fn set_reservation(&mut self, val: Option<i64>) -> &mut Self

pub fn set_swap(&mut self, val: Option<i64>) -> &mut Self

Total memory limit (memory + swap).

pub fn set_kernel(&mut self, val: Option<i64>) -> &mut Self

Kernel memory limit (in bytes).

Deprecated

kernel-memory limits are not supported in cgroups v2, and were obsoleted in kernel v5.4.

pub fn set_kernel_tcp(&mut self, val: Option<i64>) -> &mut Self

How aggressive the kernel will swap memory pages.

pub fn set_disable_oom_killer(&mut self, val: Option<bool>) -> &mut Self

DisableOOMKiller disables the OOM killer for out of memory conditions.

pub fn set_use_hierarchy(&mut self, val: Option<bool>) -> &mut Self

Enables hierarchical memory accounting

pub fn set_check_before_update(&mut self, val: Option<bool>) -> &mut Self

Trait Implementations

impl Clone for LinuxMemory

fn clone(&self) -> LinuxMemory

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LinuxMemory

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

Formats the value using the given formatter.

impl Default for LinuxMemory

fn default() -> LinuxMemory

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for LinuxMemory

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for LinuxMemory

fn eq(&self, other: &LinuxMemory) -> 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 Serialize for LinuxMemory

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
