Trait for file handles that support async read/write/seek operations.

Required Methods

fn sync_all(&self) -> impl Future<Output = Result<()>> + Send

Flush all OS-internal metadata and data to disk.

fn sync_data(&self) -> impl Future<Output = Result<()>> + Send

Flush all data to disk (metadata may not be synced).

fn size(&self) -> impl Future<Output = Result<u64>> + Send

Get the current size of the file in bytes.

fn set_len(&self, size: u64) -> impl Future<Output = Result<()>> + Send

Set the length of the file.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
