Struct DataStore 

pub struct DataStore { /* private fields */ }

Where a page keeps its cookies, storage and cache.

The default is the platform’s own store, shared by every page built with it.

Implementations

impl DataStore

pub fn new() -> Self

pub fn incognito(self) -> Self

Kept in memory and gone with the page. Overrides the directory and the identifier. On Windows, needs WebView2 Runtime 101.0.1210.39 or later, and is ignored before it.

pub fn with_directory(self, directory: impl Into<PathBuf>) -> Self

Windows: the directory the store lives in. Pages built with one directory share one store. Ignored on macOS.

pub fn with_identifier(self, identifier: [u8; 16]) -> Self

macOS 14 and later: the persistent store with this identifier, a UUID’s bytes. Pages built with one identifier share one store. Ignored elsewhere, and on earlier macOS, where the page uses the default store.

pub fn clear(&self, cx: &App) -> Task<bool>

Clears the cookies, storage and cache this store keeps. Every page built with the store must be closed first. Resolves to whether it was cleared: an incognito store keeps nothing and resolves true. Resolves false off macOS.

On macOS before 14 an identifier’s store is the default one.

pub fn usage(&self, cx: &App) -> Task<Option<Usage>>

What this store holds. Resolves None where the platform cannot tell: off macOS. An incognito store holds nothing.
