Struct MemcgConfig 

pub struct MemcgConfig {
    pub field: Vec<i32>,
    pub android_scope: Vec<AndroidScope>,
    pub poll_period_ms: Option<u32>,
}

Config for recording memory controller (memcg) values for a set of cgroups.

Fields

field: Vec<i32>

What values to record, the enum covers both single-valued files (e.g. memory.current) and files with multiple values (e.g. memory.stat). If unset, defaults to {MEMCG_CURRENT, MEMCG_STAT_ANON, MEMCG_STAT_FILE}.

android_scope: Vec<AndroidScope>

Android: Which cgroups to record. Can be specified multiple times. If scopes overlap, a given cgroup will be recorded at most once. If unset, defaults to uid-level for all uids.

poll_period_ms: Option<u32>

How often to poll the selected cgroups. If zero or unset, records values once. The implementation enforces a minimum on the period (100 ms at the time of writing).

Implementations

impl MemcgConfig

pub fn field( &self, ) -> FilterMap<Cloned<Iter<'_, i32>>, fn(i32) -> Option<MemcgField>>

Returns an iterator which yields the valid enum values contained in field.

pub fn push_field(&mut self, value: MemcgField)

Appends the provided enum value to field.

pub fn poll_period_ms(&self) -> u32

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

Trait Implementations

impl Clone for MemcgConfig

fn clone(&self) -> Self

Returns a duplicate of the value.
