Resource type definition

A Resource value represents a resource whose limit can be retrieved or set using getrlimit and setrlimit.

This enum contains all possible resource types that may or may not be available depending on the platform.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

AS

Maximum total memory size of the process

CORE

Maximum size of a core file created by a terminated process

CPU

Maximum amount of CPU time the process can consume

DATA

Maximum size of a data segment of the process

FSIZE

Maximum size of a file the process can create

KQUEUES

Maximum number of kernel event queues (kqueues)

LOCKS

Maximum number of file locks the process can hold

MEMLOCK

Maximum size of memory locked into RAM

MSGQUEUE

Maximum total size of POSIX message queues

NICE

Maximum process priority

This resource specifies the highest priority that a process can set using setpriority or nice. When the resource value is set to n, the process can lower its nice value (that is, raise the priority) to (20 - n).

NOFILE

Maximum number of open files in the process

NPROC

Maximum number of processes the user can run

RSS

Maximum physical memory size of the process

RTPRIO

Maximum real-time priority

RTTIME

Maximum amount of CPU time the process can consume in real-time scheduling mode without a blocking system call (microseconds)

SBSIZE

Maximum size of the socket buffer

SIGPENDING

Maximum number of signals that can be queued to the process

STACK

Maximum size of the process stack

SWAP

Maximum size of the swap space that can be used by the user

Implementations

impl Resource

pub const ALL: &'static [Resource]

Slice of all resource types (including those not available on the current platform)

Trait Implementations

impl Clone for Resource

fn clone(&self) -> Resource

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Resource

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

Formats the value using the given formatter.

impl Hash for Resource

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 Resource

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

impl Copy for Resource

impl Eq for Resource

impl StructuralPartialEq for Resource
