The Storage
interface of the Web Storage API provides access to
the session storage or local storage for a particular domain.
Methods
impl Storage
[src]
pub fn len(&self) -> u32
[src]
Gets the number of data items stored in the Storage
object.
pub fn get(&self, key: &str) -> Option<String>
[src]
Returns a value corresponding to the key.
pub fn insert(&self, key: &str, value: &str) -> Result<(), TODO>
[src]
Inserts a key-value pair into the storage.
pub fn remove(&self, key: &str)
[src]
Removes a key from the storage.
pub fn clear(&self)
[src]
When invoked, will empty all keys out of the storage.
pub fn key(&self, nth: u32) -> Option<String>
[src]
Return the name of the nth key in the storage.
pub fn contains_key(&self, key: &str) -> bool
[src]
Returns true if the storage contains a value for the specified key.
