Struct ResourceLimits 

pub struct ResourceLimits {
    pub max_memory_bytes: u64,
    pub max_file_descriptors: u64,
    pub max_processes: u64,
    pub execution_timeout: Duration,
}

Resource limits for DOS attack prevention

Enforces strict limits on resources that can be consumed during analysis:

• Memory usage (prevents memory exhaustion)
• File descriptors (prevents FD exhaustion)
• Process count (prevents fork bombs)
• Execution timeout (prevents infinite loops)

Fields

max_memory_bytes: u64

Maximum memory usage in bytes (default: 500MB)

max_file_descriptors: u64

Maximum number of file descriptors (default: 1024)

max_processes: u64

Maximum number of processes (default: 100)

execution_timeout: Duration

Maximum execution time (default: 300s)

Implementations

impl ResourceLimits

pub fn new( max_memory_bytes: u64, max_file_descriptors: u64, max_processes: u64, execution_timeout: Duration, ) -> Self

Create new resource limits with custom values

pub fn apply(&self) -> Result<()>

Apply resource limits to the current process (Unix only)

This method uses setrlimit to enforce hard limits on resources. On non-Unix platforms, this is a no-op.

pub fn timeout(&self) -> Duration

Get timeout duration

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.
