Expand description

A data structure with a file representation which can be loaded from and flushed to disk asynchronously.

Required Associated Types§

Source

type Err: Error

Required Methods§

Source

fn load<'async_trait>( path: impl 'async_trait + AsRef<Path> + Send, ) -> Pin<Box<dyn Future<Output = Result<Self, Self::Err>> + Send + 'async_trait>>
where Self: 'async_trait,

Load the data structure from disk asynchronously.

If you wish to perform non-trivial deserialisation in this function, you should spawn a blocking task with your async runtime.

Source

fn flush<'life0, 'async_trait>( self: &'life0 Arc<Self>, path: impl 'async_trait + AsRef<Path> + Send, ) -> Pin<Box<dyn Future<Output = Result<(), Self::Err>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait,

Flush the data structure to disk asynchronously.

If you wish to perform non-trivial serialisation in this function, you should spawn a blocking task with your async runtime.

Source

fn delete<'async_trait>( path: impl 'async_trait + AsRef<Path> + Send, ) -> Pin<Box<dyn Future<Output = Result<(), Self::Err>> + Send + 'async_trait>>
where Self: 'async_trait,

Delete the data structure from disk asynchronously.

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
