Enum nix::sys::reboot::RebootMode

#[repr(i32)]
#[non_exhaustive]
pub enum RebootMode {
    RB_HALT_SYSTEM,
    RB_KEXEC,
    RB_POWER_OFF,
    RB_AUTOBOOT,
    RB_SW_SUSPEND,
}

How exactly should the system be rebooted.

See set_cad_enabled() for enabling/disabling Ctrl-Alt-Delete.

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.

RB_HALT_SYSTEM

Halt the system.

RB_KEXEC

Execute a kernel that has been loaded earlier with kexec_load(2).

RB_POWER_OFF

Stop the system and switch off power, if possible.

RB_AUTOBOOT

Restart the system.

RB_SW_SUSPEND

Suspend the system using software suspend.

Trait Implementations

impl Clone for RebootMode

fn clone(&self) -> RebootMode

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for RebootMode

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

Formats the value using the given formatter.

impl Hash for RebootMode

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,

Feeds a slice of this type into the given Hasher.

impl Ord for RebootMode

fn cmp(&self, other: &RebootMode) -> 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) -> Selfwhere
    Self: PartialOrd<Self>,

Restrict a value to a certain interval.

impl PartialEq<RebootMode> for RebootMode

fn eq(&self, other: &RebootMode) -> 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<RebootMode> for RebootMode

fn partial_cmp(&self, other: &RebootMode) -> 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.
