Struct ResourceLimits 

pub struct ResourceLimits {
    pub max_duration: Option<Duration>,
    pub max_memory: Option<usize>,
    pub gc_interval: Option<usize>,
    pub max_recursion_depth: usize,
}

Configuration for resource limits.

The time/memory/GC limits are optional — set to None to disable — but recursion depth is always bounded (default DEFAULT_MAX_RECURSION_DEPTH): unbounded recursion would let sandboxed code overflow the native stack and abort the process. Use ResourceLimits::default() for the recursion-only defaults, or build custom limits with the builder pattern.

Fields

max_duration: Option<Duration>

Maximum execution time.

max_memory: Option<usize>

Maximum allocator-backed memory in bytes.

Requires the executable to install and arm monty-alloc.

gc_interval: Option<usize>

Run garbage collection every N GC-tracked allocations.

max_recursion_depth: usize

Maximum recursion depth (function call stack depth).

Implementations

impl ResourceLimits

pub fn max_duration(self, limit: Duration) -> Self

Sets the maximum execution duration.

pub fn max_memory(self, limit: usize) -> Self

Sets allocator-backed maximum memory usage in bytes.

Requires the executable to install and arm monty-alloc; otherwise the limit is silently not enforced.

pub fn gc_interval(self, interval: usize) -> Self

Sets the garbage collection interval (run GC every N GC-tracked allocations).

pub fn max_recursion_depth(self, limit: usize) -> Self

Sets the maximum recursion depth (function call stack depth).

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

Creates a new ResourceLimits with all limits disabled, except max recursion which is set to 1000.

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 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.
