Struct StorageNamespace 

pub struct StorageNamespace(/* private fields */);

Namespace for isolating storage domains. Prevents key collisions between different parts of the app.

Implementations

impl StorageNamespace

pub fn new(name: impl Into<String>) -> Self

pub fn app_data() -> Self

Default namespace for app data.

pub fn preferences() -> Self

Namespace for user preferences.

pub fn cache() -> Self

Namespace for cache data (can be cleared by system).

pub fn as_str(&self) -> &str

pub fn prefixed_key(&self, key: &str) -> String

Build a namespaced key: “namespace:key”

Trait Implementations

impl Clone for StorageNamespace

fn clone(&self) -> StorageNamespace

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for StorageNamespace

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

Formats the value using the given formatter.

impl Default for StorageNamespace

fn default() -> Self

Returns the “default value” for a type.

impl Hash for StorageNamespace

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 StorageNamespace

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