Struct ProcessLimits 

pub struct ProcessLimits {
    pub max_memory_percent: Option<u32>,
    pub max_cpu_percent: Option<u32>,
    pub enabled: bool,
}

Configuration for process resource limits

Fields

max_memory_percent: Option<u32>

Maximum memory usage as percentage of total system memory (None = no limit) Default is 50% of total system memory

max_cpu_percent: Option<u32>

Maximum CPU usage as percentage of total CPU (None = no limit) For multi-core systems, 100% = 1 core, 200% = 2 cores, etc.

enabled: bool

Enable resource limiting (can be disabled per-platform)

Implementations

impl ProcessLimits

pub fn unlimited() -> Self

Create a new ProcessLimits with no restrictions

pub fn default_cpu_limit_percent() -> u32

Get the default CPU limit (90% of total CPU)

impl ProcessLimits

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

Get the memory limit in bytes, computed from percentage of total system memory

pub fn apply_to_command(&self, _cmd: &mut Command) -> Result<PostSpawnAction>

Apply these limits to a tokio Command before spawning

On Linux, tries user-delegated cgroups v2, otherwise falls back to setrlimit. Memory and CPU limits are handled independently.

Returns a PostSpawnAction that the caller must apply to the child process after cmd.spawn() returns. (For cgroups, the actual per-child assignment happens from the parent using the child’s PID; doing it in pre_exec is not fork-safe.)

Trait Implementations

impl Clone for ProcessLimits

fn clone(&self) -> ProcessLimits

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ProcessLimits

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

Formats the value using the given formatter.

impl Default for ProcessLimits

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for ProcessLimits

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl JsonSchema for ProcessLimits

fn schema_name() -> Cow<'static, str>

The name of the generated JSON Schema.

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

fn json_schema(generator: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn inline_schema() -> bool

Whether JSON Schemas generated for this type should be included directly in parent schemas, rather than being re-used where possible using the $ref keyword.

impl PartialEq for ProcessLimits

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
