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_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.
