Struct wlan_stash::policy::PolicyStorage

pub struct PolicyStorage { /* private fields */ }

Manages access to the persistent storage or saved network configs through Stash

Implementations

impl PolicyStorage

pub async fn new_with_id_and_proxy( id: &str, proxy_fn: impl FnOnce() -> Result<SecureStoreProxy, Error> ) -> Result<Self, Error>

Initialize new store with the ID provided by the Saved Networks Manager. The ID will identify stored values as being part of the same persistent storage. proxy_fn is used to connect to stash if necessary.

pub async fn new_with_id(id: &str) -> Result<Self, Error>

Like new_with_id_and_proxy but provides a default proxy_fn.

pub fn new_with_stash(proxy: StoreAccessorProxy) -> Self

Initialize new Stash with a provided proxy in order to mock stash in unit tests.

pub async fn write( &self, id: &NetworkIdentifier, network_configs: &[PersistentData] ) -> Result<(), Error>

Update the network configs of a given network identifier to persistent storage, deleting the key entirely if the new list of configs is empty.

pub async fn load( &self ) -> Result<HashMap<NetworkIdentifier, Vec<PersistentData>>, Error>

Load all saved network configs from stash. Will create HashMap of network configs by SSID as saved in the stash. If something in stash can’t be interpreted, we ignore it.

pub async fn clear(&mut self) -> Result<(), Error>

Remove all saved values from the stash. It will delete everything under the root node, and anything else in the same stash but not under the root node would be ignored.
