Struct settings_storage::device_storage::DeviceStorage

pub struct DeviceStorage { /* private fields */ }

Stores device level settings in persistent storage. User level settings should not use this.

Implementations

impl DeviceStorage

pub fn with_stash_proxy<I, G>( iter: I, stash_generator: G, inspect_handle: Arc<Mutex<StashInspectLogger>> ) -> Self

where I: IntoIterator<Item = &'static str>, G: Fn() -> StoreAccessorProxy,

Construct a device storage from the iteratable item, which will produce the keys for storage, and from a generator that will produce a stash proxy given a particular key.

pub fn set_caching_enabled(&mut self, enabled: bool)

Test-only

pub fn set_debounce_writes(&mut self, debounce: bool)

Test-only

pub async fn write<T>(&self, new_value: &T) -> Result<UpdateState, Error>

where T: DeviceStorageCompatible,

Write new_value to storage. The write will be persisted to disk at a set interval.

pub async fn write_str( &self, key: &'static str, value: String ) -> Result<(), Error>

Test-only method to write directly to stash without touching the cache. This is used for setting up data as if it existed on disk before the connection to stash was made.

pub async fn get<T>(&self) -> T

where T: DeviceStorageCompatible,

Gets the latest value cached locally, or loads the value from storage. Doesn’t support multiple concurrent callers of the same struct.
