Enum type used for resource values.

Variants

AS

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

CORE

The maximum size (in bytes) of a core file that the process may dump.

CPU

A limit (in seconds) on the amount of CPU time that the process can consume.

DATA

The maximum size (in bytes) of the process's data segment (initialized data, uninitialized data, and heap).

FSIZE

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

LOCKS

A limit on the combined number of flock(2) locks and fcntl(2) leases that this process may establish.

MEMLOCK

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

MSGQUEUE

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

NICE

This specifies a ceiling to which the process's nice value can be raised using setpriority(2) or nice(2).

NOFILE

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

NPROC

A limit on the number of extant process (or, more precisely on Linux, threads) for the real user ID of the calling process.

RSS

A limit (in bytes) on the process's resident set (the number of virtual pages resident in RAM).

RTPRIO

This specifies a ceiling on the real-time priority that may be set for this process using sched_setscheduler(2) and sched_setparam(2).

RTTIME

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

SIGPENDING

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

STACK

The maximum size (in bytes) of the process stack.

Methods

impl Resource

pub fn as_raw_resource(&self) -> RawResource

pub fn set(&self, soft: rlim, hard: rlim) -> Result<()>

Trait Implementations

impl Clone for Resource

fn clone(&self) -> Resource

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Ord for Resource

fn cmp(&self, other: &Resource) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

🔬 This is a nightly-only experimental API. (clamp)

Restrict a value to a certain interval.

impl PartialOrd<Resource> for Resource

fn partial_cmp(&self, other: &Resource) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

#[must_use] fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

#[must_use] fn le(&self, other: &Rhs) -> bool

#[must_use] fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

#[must_use] fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl PartialEq<Resource> for Resource

fn eq(&self, other: &Resource) -> bool

This method tests for self and other values to be equal, and is used by ==.

#[must_use] fn ne(&self, other: &Rhs) -> bool

This method tests for !=.

impl Copy for Resource

impl Eq for Resource
