Struct Permission

pub struct Permission { /* private fields */ }

A GPermission represents the status of the caller’s permission to perform a certain action.

You can query if the action is currently allowed and if it is possible to acquire the permission so that the action will be allowed in the future.

There is also an API to actually acquire the permission and one to release it.

As an example, a GPermission might represent the ability for the user to write to a Settings object. This GPermission object could then be used to decide if it is appropriate to show a “Click here to unlock” button in a dialog and to provide the mechanism to invoke when that button is clicked.

This is an Abstract Base Class, you cannot instantiate it.

Properties

allowed

true if the caller currently has permission to perform the action that @permission represents the permission to perform.

Readable

can-acquire

true if it is generally possible to acquire the permission by calling g_permission_acquire().

Readable

can-release

true if it is generally possible to release the permission by calling g_permission_release().

Readable

Implements

PermissionExt, [trait@glib::ObjectExt]

GLib type: GObject with reference counted clone semantics.

Implementations

impl Permission

pub const NONE: Option<&'static Permission> = None

Trait Implementations

impl Clone for Permission

fn clone(&self) -> Self

Makes a clone of this shared reference.

This increments the strong reference count of the object. Dropping the object will decrement it again.

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

Performs copy-assignment from source.

impl Debug for Permission

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

Formats the value using the given formatter.

impl HasParamSpec for Permission

type ParamSpec = ParamSpecObject

type SetValue = Permission

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

type BuilderFn = fn(_: &str) -> ParamSpecObjectBuilder<'_, Permission>

fn param_spec_builder() -> Self::BuilderFn

impl Hash for Permission

fn hash<H>(&self, state: &mut H)

where H: Hasher,

Hashes the memory address of this object.

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 Permission

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

Comparison for two GObjects.

Compares the memory addresses of the provided objects.

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

where Self: Sized,

Compares and returns the maximum of two values.

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

where Self: Sized,

Compares and returns the minimum of two values.

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

where Self: Sized,

Restrict a value to a certain interval.

impl ParentClassIs for Permission

type Parent = Object

impl<OT: ObjectType> PartialEq<OT> for Permission

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

Equality for two GObjects.

Two GObjects are equal if their memory addresses are equal.

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<OT: ObjectType> PartialOrd<OT> for Permission

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

Partial comparison for two GObjects.

Compares the memory addresses of the provided objects.

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

Tests less than (for self and other) and is used by the < operator.

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

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

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

Tests greater than (for self and other) and is used by the > operator.

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

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

impl StaticType for Permission

fn static_type() -> Type

Returns the type identifier of Self.

impl Eq for Permission

impl IsA<Permission> for SimplePermission
