Struct stdweb::web::Storage [−][src]
pub struct Storage(_);
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]
impl Storagepub fn len(&self) -> u32[src]
pub fn len(&self) -> u32Gets the number of data items stored in the Storage object.
pub fn get(&self, key: &str) -> Option<String>[src]
pub fn get(&self, key: &str) -> Option<String>Returns a value corresponding to the key.
pub fn insert(&self, key: &str, value: &str) -> Result<(), TODO>[src]
pub fn insert(&self, key: &str, value: &str) -> Result<(), TODO>Inserts a key-value pair into the storage.
pub fn remove(&self, key: &str)[src]
pub fn remove(&self, key: &str)Removes a key from the storage.
pub fn clear(&self)[src]
pub fn clear(&self)When invoked, will empty all keys out of the storage.
pub fn key(&self, nth: u32) -> Option<String>[src]
pub fn key(&self, nth: u32) -> Option<String>Return the name of the nth key in the storage.
pub fn contains_key(&self, key: &str) -> bool[src]
pub fn contains_key(&self, key: &str) -> boolReturns true if the storage contains a value for the specified key.
