Struct ConfidentialCell

Source 
pub struct ConfidentialCell<'key, T> { /* private fields */ }
Expand description

A storage cell identifies a storage key of a specific type.

Implementations§

Source§

impl<'key, T> ConfidentialCell<'key, T>

Source

pub const fn new(key: &'key [u8]) -> Self

Create a new storage cell with the specified key and type.

Source

pub fn clear(&self, store: &mut dyn ConfidentialStore)

Source§

impl<'key, T> ConfidentialCell<'key, T>
where T: Decode,

Source

pub fn get(&self, store: &dyn ConfidentialStore) -> Option<T>

Return the current value of the storage cell.

§Panics

The method will panic in case the raw cell value cannot be deserialized.

Source§

impl<'key, T> ConfidentialCell<'key, T>
where T: Encode,

Source

pub fn set(&self, store: &mut dyn ConfidentialStore, value: T)

Set the value of the storage cell.
