Enum AppDir 

#[non_exhaustive]
pub enum AppDir {
    Data,
    Cache,
    PublicMedia,
}

Directory for the app’s use.

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 directory for persistent-data files.

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

This may be accessible by other apps.

e.g.

• /storage/emulated/{user-id}/Android/data/{app-package-name}/files
• /storage/{sd-card-id}/Android/data/{app-package-name}/files

https://developer.android.com/reference/android/content/Context#getExternalFilesDirs(java.lang.String)

Cache

The directory for cache files.

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

This may be accessible by other apps.

e.g.

• /storage/emulated/{user-id}/Android/data/{app-package-name}/cache
• /storage/{sd-card-id}/Android/data/{app-package-name}/cache

PublicMedia

👎Deprecated:

For Android 11 (API level 30) or higher, this is deprecated. Use PublicDir of PublicStorage instead.

The directory for shared media files to other apps or user.

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

For Android 11 (API level 30) or higher, this has been marked as deprecated. It still works, but you should consider migrating to PublicStorage.

e.g.

• /storage/emulated/{user-id}/Android/media/{app-package-name}
• /storage/{sd-card-id}/Android/media/{app-package-name}

Trait Implementations

impl Clone for AppDir

fn clone(&self) -> AppDir

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for AppDir

impl Debug for AppDir

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for AppDir

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for AppDir

impl Hash for AppDir

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 AppDir

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
