Struct WebStorage 

pub struct WebStorage { /* private fields */ }

A handle to one of a page’s web storages (localStorage or sessionStorage) for a given origin.

Cheaply cloneable; all clones share the same page session, origin, and storage kind.

Implementations

impl WebStorage

pub async fn get(&self, key: &str) -> Result<Option<String>>

The value for key, or None if absent.

pub async fn set(&self, key: &str, value: &str) -> Result<()>

Set key to value, overwriting any existing value. Issues DOMStorage.setDOMStorageItem.

pub async fn remove(&self, key: &str) -> Result<()>

Remove key (no-op if absent). Issues DOMStorage.removeDOMStorageItem.

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

Remove all entries. Issues DOMStorage.clear.

pub async fn keys(&self) -> Result<Vec<String>>

All keys currently in storage.

pub async fn size(&self) -> Result<usize>

The number of entries in storage.

pub async fn has(&self, key: &str) -> Result<bool>

Whether key is present.

pub fn security_origin(&self) -> &str

The security origin this storage is scoped to.

pub fn is_local_storage(&self) -> bool

true if this is localStorage, false for sessionStorage.

Trait Implementations

impl Clone for WebStorage

fn clone(&self) -> WebStorage

Returns a duplicate of the value.

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

Performs copy-assignment from source.
