}

Resource-update payload passed to Runtime::update_container_resources.

Mirrors the resource subset of Docker’s POST /containers/{id}/update body. Every field is Option<...>; backends apply only the fields that are Some. A request with all fields None is a no-op (consistent with Docker’s behaviour).

Field semantics match Docker’s wire shape: see [ContainerUpdateRequest] in zlayer-types::api::containers for the JSON encoding.

Fields

cpu_shares: Option<i64>

CPU shares (cgroup cpu.weight / cpu.shares).

memory: Option<i64>

Memory limit in bytes.

cpu_period: Option<i64>

CPU CFS period in microseconds.

cpu_quota: Option<i64>

CPU CFS quota in microseconds.

cpu_realtime_period: Option<i64>

CPU real-time period in microseconds.

cpu_realtime_runtime: Option<i64>

CPU real-time runtime in microseconds.

cpuset_cpus: Option<String>

CPUs allowed for execution (e.g. "0-3").

cpuset_mems: Option<String>

Memory nodes (NUMA) allowed for execution.

memory_reservation: Option<i64>

Soft memory limit in bytes.

memory_swap: Option<i64>

Total memory limit (memory + swap) in bytes. -1 removes swap.

kernel_memory: Option<i64>

Kernel memory limit in bytes (deprecated upstream).

blkio_weight: Option<u16>

Block IO weight (10-1000).

pids_limit: Option<i64>

PIDs limit. 0 or -1 for unlimited.

restart_policy: Option<ContainerRestartPolicyUpdate>

Replacement restart policy. None leaves the policy unchanged.

Implementations

impl ContainerResourceUpdate

pub fn is_empty(&self) -> bool

Returns true when this update would not change anything — every field is None. Backends short-circuit no-op updates rather than touching the cgroup hierarchy.

Trait Implementations

impl Clone for ContainerResourceUpdate

fn clone(&self) -> ContainerResourceUpdate

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ContainerResourceUpdate

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

Formats the value using the given formatter.

impl Default for ContainerResourceUpdate

fn default() -> ContainerResourceUpdate

Returns the “default value” for a type.

impl PartialEq for ContainerResourceUpdate

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