Types of process resources.

The Resource enum is platform dependent. Check different platform manuals for more details. Some platform links have been provided for easier reference (non-exhaustive).

• Linux
• FreeBSD
• NetBSD

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.

RLIMIT_AS

The maximum amount (in bytes) of virtual memory the process is allowed to map.

RLIMIT_CORE

The largest size (in bytes) core(5) file that may be created.

RLIMIT_CPU

The maximum amount of cpu time (in seconds) to be used by each process.

RLIMIT_DATA

The maximum size (in bytes) of the data segment for a process

RLIMIT_FSIZE

The largest size (in bytes) file that may be created.

RLIMIT_NOFILE

The maximum number of open files for this process.

RLIMIT_STACK

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

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 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 Ord for Resource

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

This method returns an Ordering between self and other.

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

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere
    Self: Sized + PartialOrd<Self>,

Restrict a value to a certain interval.

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 ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

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.

fn lt(&self, other: &Rhs) -> bool

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

fn le(&self, other: &Rhs) -> bool

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

fn gt(&self, other: &Rhs) -> bool

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

fn ge(&self, other: &Rhs) -> bool

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