Process limits information See man 2 getrlimit.

Fields

max_cpu_time: Limit<Duration>

The maximum CPU time a process can use.

max_file_size: Limit<u64>

The maximum size of files that the process may create in bytes.

max_data_size: Limit<usize>

The maximum size of the process’s data segment in bytes.

max_stack_size: Limit<usize>

The maximum size of the process stack in bytes.

max_core_file_size: Limit<usize>

Maximum size of a core file in bytes.

max_resident_set: Limit<usize>

Specifies the limit of the process’s resident set in bytes.

max_processes: Limit<usize>

The maximum number of processes (or, more precisely on Linux, threads) that can be created for the real user ID of the calling process.

max_open_files: Limit<usize>

Specifies a value one greater than the maximum file descriptor number that can be opened by this process.

max_locked_memory: Limit<usize>

The maximum number of bytes of memory that may be locked into RAM.

max_address_space: Limit<usize>

The maximum size of the process’s virtual memory (address space) in bytes.

max_file_locks: Limit<usize>

A limit on the combined number of locks and leases that this process may establish.

max_pending_signals: Limit<usize>

Specifies the limit on the number of signals that may be queued for the real user ID of the calling process.

max_msgqueue_size: Limit<usize>

Specifies the limit on the number of bytes that can be allocated for POSIX message queues for the real user ID of the calling process.

max_nice_priority: Limit<usize>

Specifies a ceiling to which the process’s nice value can be raised.

max_realtime_priority: Limit<usize>

Specifies a limit on the amount of CPU time that a process scheduled under a real-time scheduling policy may consume without making a blocking system call.

max_realtime_timeout: Limit<Duration>

Specifies a ceiling on the real-time priority that may be set for this process.

Trait Implementations

impl Clone for Limits

fn clone(&self) -> Limits

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Limits

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

Formats the value using the given formatter.

impl Hash for Limits

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Limits

fn eq(&self, other: &Limits) -> 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.
