Enum PrivateDir 

#[non_exhaustive]
pub enum PrivateDir {
    Data,
    Cache,
    NoBackupData,
}

The application specific directory.

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.

Data

The application specific persistent-data directory.

Files stored in this directory are included in Android Auto Backup.

The system prevents other apps and user from accessing these locations. In cases where the device is rooted or the user has special permissions, the user may be able to access this.

These files will be deleted when the app is uninstalled and may also be deleted at the user’s request.

e.g. /data/user/0/{app-package-name}/files

Cache

The application specific cache directory.

Files stored in this directory are not included in Android Auto Backup.

The system prevents other apps and user from accessing these locations. In cases where the device is rooted or the user has special permissions, the user may be able to access this.

These files will be deleted when the app is uninstalled and may also be deleted at the user’s request. In addition, the system will automatically delete files in this directory as disk space is needed elsewhere on the device.

e.g. /data/user/0/{app-package-name}/cache

https://developer.android.com/reference/android/content/Context#getCacheDir()

NoBackupData

The application specific persistent-data directory.

This is similar to PrivateDir::Data. But files stored in this directory are not included in Android Auto Backup.

The system prevents other apps and user from accessing these locations. In cases where the device is rooted or the user has special permissions, the user may be able to access this.

These files will be deleted when the app is uninstalled and may also be deleted at the user’s request.

e.g. /data/user/0/{app-package-name}/no_backup

Trait Implementations

impl Clone for PrivateDir

fn clone(&self) -> PrivateDir

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PrivateDir

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for PrivateDir

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for PrivateDir

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 PartialEq for PrivateDir

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

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

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

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