Struct Current

pub struct Current {
    store: RwLock<Store>,
}

A holder for a Store, which allows the store to be updated on the fly.

Fields

store: RwLock<Store>

Implementations

impl Current

pub const fn new(store: Store) -> Self

Create a new Current. The store passed into this function will be returned by calls to get.

pub fn new_static(store: Store) -> &'static Self

Create a new static reference to a new Current. The store passed into this function will be returned by calls to get.

Memory

This function leaks memory. Make sure it is not called an unbounded number of times.

pub fn get(&self) -> Store

Get the current Store. The returned store itself will remain unchanged even if the Current is updated.

pub fn update(&self, store: Store)

Update the store inside this Current. All future calls to get will return this store instead, but all still-active stores will remain unchanged.

pub fn backend_name(&self) -> &'static str

Get the current store’s backend name. This is (slightly) more efficient than current.get().backend_name(), because it doesn’t need to update the store’s internal reference count.

Trait Implementations

impl Debug for Current

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
