Struct ResourceLimits 

pub struct ResourceLimits {
    pub max_memory_mb: u64,
    pub max_pids: u32,
    pub max_disk_mb: u64,
    pub cpu_time_secs: u64,
    pub timeout_secs: u64,
}

Resource limits for sandboxed execution.

Following the field guide’s recommendation for resource accounting: “CPU, memory, disk, timeouts, and PIDs.”

Fields

max_memory_mb: u64

Maximum memory usage in megabytes (0 = unlimited).

max_pids: u32

Maximum number of processes/threads (0 = unlimited). Prevents fork bombs.

max_disk_mb: u64

Maximum disk write in megabytes (0 = unlimited).

cpu_time_secs: u64

CPU time limit in seconds (0 = unlimited).

timeout_secs: u64

Wall clock timeout in seconds (0 = use default).

Implementations

impl ResourceLimits

pub fn unlimited() -> Self

Create new resource limits with all values unlimited.

pub fn conservative() -> Self

Create conservative limits suitable for untrusted code. Following field guide: “Resource limits: CPU, memory, disk, timeouts, and PIDs.”

pub fn moderate() -> Self

Create moderate limits for semi-trusted code.

pub fn generous() -> Self

Create generous limits for trusted internal code.

pub fn with_memory_mb(self, mb: u64) -> Self

Builder: set memory limit.

pub fn with_max_pids(self, pids: u32) -> Self

Builder: set PID limit.

pub fn with_disk_mb(self, mb: u64) -> Self

Builder: set disk limit.

pub fn with_cpu_time_secs(self, secs: u64) -> Self

Builder: set CPU time limit.

pub fn with_timeout_secs(self, secs: u64) -> Self

Builder: set timeout.

pub fn has_limits(&self) -> bool

Check if any limits are set.

pub fn effective_timeout_secs(&self) -> u64

Get the effective timeout in seconds.

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() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for ResourceLimits

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for ResourceLimits

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.

impl Serialize for ResourceLimits

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
