Enum gio::MemoryMonitorWarningLevel

#[non_exhaustive]
pub enum MemoryMonitorWarningLevel {
    Low,
    Medium,
    Critical,
}

Available on crate feature v2_64 only.

Memory availability warning levels.

Note that because new values might be added, it is recommended that applications check MemoryMonitorWarningLevel as ranges, for example:

⚠️ The following code is in C ⚠️

if (warning_level > G_MEMORY_MONITOR_WARNING_LEVEL_LOW)
  drop_caches ();

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.

Low

Memory on the device is low, processes should free up unneeded resources (for example, in-memory caches) so they can be used elsewhere.

Medium

Same as Low but the device has even less free memory, so processes should try harder to free up unneeded resources. If your process does not need to stay running, it is a good time for it to quit.

Critical

The system will soon start terminating processes to reclaim memory, including background processes.

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

Formats the value using the given formatter.

impl From<MemoryMonitorWarningLevel> for Value

fn from(v: MemoryMonitorWarningLevel) -> Self

Converts to this type from the input type.

impl<'a> FromValue<'a> for MemoryMonitorWarningLevel

type Checker = GenericValueTypeChecker<MemoryMonitorWarningLevel>

Value type checker.

unsafe fn from_value(value: &'a Value) -> Self

Get the contained value from a Value.

impl HasParamSpec for MemoryMonitorWarningLevel

type ParamSpec = ParamSpecEnum

type SetValue = MemoryMonitorWarningLevel

Preferred value to be used as setter for the associated ParamSpec.

type BuilderFn = fn(_: &str, _: MemoryMonitorWarningLevel) -> ParamSpecEnumBuilder<'_, MemoryMonitorWarningLevel>

fn param_spec_builder() -> Self::BuilderFn

impl Hash for MemoryMonitorWarningLevel

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 MemoryMonitorWarningLevel

fn cmp(&self, other: &MemoryMonitorWarningLevel) -> 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<MemoryMonitorWarningLevel> for MemoryMonitorWarningLevel

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

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.

Returns the type identifier of Self.

impl ToValue for MemoryMonitorWarningLevel

fn to_value(&self) -> Value

Convert a value to a Value.

fn value_type(&self) -> Type
