Struct folda::Persistent

pub struct Persistent<'store, Key, Value> where
    Key: Copy + Eq + Hash + 'static,
    Value: 'static,  { /* fields omitted */ }

A warpper represents managed data. This struct gives exclusive, mutable access to the value. When user want to use some sort of data stored in the DB, it should always be warpped in this type. When the value is dropped, it's stored to a persistent storage.

Methods

impl<'store, Key, Value> Persistent<'store, Key, Value> where
    Key: Copy + Eq + Hash + 'static,
    Value: 'static, 

pub fn get_key(&self) -> Key

Trait Implementations

impl<'store, Key, Value> Drop for Persistent<'store, Key, Value> where
    Key: Copy + Eq + Hash + 'static,
    Value: 'static, 

fn drop(&mut self)

Executes the destructor for this type.

impl<'store, Key, Value> Deref for Persistent<'store, Key, Value> where
    Key: Copy + Eq + Hash + 'static,
    Value: 'static, 

type Target = Value

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl<'store, Key, Value> DerefMut for Persistent<'store, Key, Value> where
    Key: Copy + Eq + Hash + 'static,
    Value: 'static, 

fn deref_mut(&mut self) -> &mut Self::Target

Mutably dereferences the value.
