Struct WrapDatabaseAsync 

pub struct WrapDatabaseAsync<T> { /* private fields */ }

Wraps a DatabaseAsync or DatabaseAsyncRef to provide a Database implementation.

Implementations

impl<T> WrapDatabaseAsync<T>

pub fn new(db: T) -> Option<WrapDatabaseAsync<T>>

Wraps a DatabaseAsync or DatabaseAsyncRef instance.

Returns None if no tokio runtime is available or if the current runtime is a current-thread runtime.

pub fn with_runtime(db: T, runtime: Runtime) -> WrapDatabaseAsync<T>

Wraps a DatabaseAsync or DatabaseAsyncRef instance, with a runtime.

Refer to [tokio::runtime::Builder] on how to create a runtime if you are in synchronous world.

If you are already using something like [tokio::main], call WrapDatabaseAsync::new instead.

pub fn with_handle(db: T, handle: Handle) -> WrapDatabaseAsync<T>

Wraps a DatabaseAsync or DatabaseAsyncRef instance, with a runtime handle.

This generally allows you to pass any valid runtime handle, refer to [tokio::runtime::Handle] on how to obtain a handle.

If you are already in asynchronous world, like [tokio::main], use WrapDatabaseAsync::new instead.
