Struct PermissionTree

pub struct PermissionTree {
    pub icon: Option<MipmapOrDrawableResource>,
    pub label: Option<StringResourceOrString>,
    pub name: Option<String>,
}

Declares the base name for a tree of permissions.

The application takes ownership of all names within the tree. It can dynamically add new permissions to the tree by calling PackageManager.addPermission() Names within the tree are separated by periods ('.'). For example, if the base name is com.example.project.taxes.

Permissions like the following might be added:

• com.example.project.taxes.CALCULATE
• com.example.project.taxes.deductions.MAKE_SOME_UP
• com.example.project.taxes.deductions.EXAGGERATE

Note that this element does not declare a permission itself, only a namespace in which further permissions can be placed. See the <permission> element for information on declaring permissions.

Fields

icon: Option<MipmapOrDrawableResource>

An icon representing all the permissions in the tree. This attribute must be set as a reference to a drawable resource containing the image definition.

label: Option<StringResourceOrString>

A user-readable name for the group. As a convenience, the label can be directly set as a raw string for quick and dirty programming. However, when the application is ready to be published, it should be set as a reference to a string resource, so that it can be localized like other strings in the user interface.

name: Option<String>

The name that’s at the base of the permission tree. It serves as a prefix to all permission names in the tree. Java-style scoping should be used to ensure that the name is unique. The name must have more than two period-separated segments in its path — for example, com.example.base is OK, but com.example is not.

Trait Implementations

impl Clone for PermissionTree

fn clone(&self) -> PermissionTree

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PermissionTree

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

Formats the value using the given formatter.

impl Default for PermissionTree

fn default() -> PermissionTree

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for PermissionTree

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for PermissionTree

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

Tests for self and other values to be equal, and is used by ==.

const 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 Serialize for PermissionTree

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl YaDeserialize for PermissionTree

fn deserialize<R: Read>(reader: &mut Deserializer<R>) -> Result<Self, String>

impl YaSerialize for PermissionTree

fn serialize<W: Write>(&self, writer: &mut Serializer<W>) -> Result<(), String>

fn serialize_attributes( &self, source_attributes: Vec<OwnedAttribute>, source_namespace: Namespace, ) -> Result<(Vec<OwnedAttribute>, Namespace), String>
