Struct ResourceLimits 

pub struct ResourceLimits {
    pub memory: Option<String>,
    pub cpus: Option<String>,
    pub cpu_weight: Option<String>,
}

Resource limits that map to systemd cgroup directives.

Each field is None when the limit is not set. Values are stored in the container’s state file and converted to a systemd drop-in at start time.

Fields

memory: Option<String>

MemoryMax=, e.g. “512M”, “2G”

cpus: Option<String>

CPUQuota=, stored as a number of CPUs (e.g. “2” → 200%)

cpu_weight: Option<String>

CPUWeight=, integer 1-10000

Implementations

impl ResourceLimits

pub fn is_empty(&self) -> bool

Returns true if no limits are set.

pub fn from_state(state: &State) -> Self

Read limits from a state file’s key-value pairs.

pub fn write_to_state(&self, state: &mut State)

Write limits into a state’s key-value pairs.

Set fields are written; unset fields are removed from the state.

pub fn dropin_content(&self) -> Option<String>

Generate the content of a systemd drop-in [Service] section.

Returns None if no limits are set.

pub fn validate(&self) -> Result<()>

Validate all set fields. Returns an error describing the first invalid value.

Trait Implementations

impl Clone for ResourceLimits

fn clone(&self) -> ResourceLimits

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ResourceLimits

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

Formats the value using the given formatter.

impl Default for ResourceLimits

fn default() -> ResourceLimits

Returns the “default value” for a type.

impl PartialEq for ResourceLimits

fn eq(&self, other: &ResourceLimits) -> 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.
