Struct FileDescriptorHandlerReadOnlyAsync 

pub struct FileDescriptorHandlerReadOnlyAsync<TId: FileIdType> { /* private fields */ }

Async read-only file-descriptor helpers.

With Linux feature io_uring, read, flush, and fsync use io_uring; other methods use synchronous unix_fs calls. On BSD/macOS they all remain synchronous.
