pub fn new(inner: T) -> Adapter<T>

Trait Implementations

impl<T: AsyncSeek + Unpin> AsyncGetSize for Adapter<T>

fn poll_get_size( self: Pin<&mut Self>, cx: &mut Context<'_>, ) -> Poll<Result<u64>>

Attempt to get the size of the file, on success returns the file size.

impl<T: AsyncRead + AsyncSeek + Unpin> AsyncReadAt for Adapter<T>

fn poll_read_at( self: Pin<&mut Self>, cx: &mut Context<'_>, offset: u64, buf: &mut [u8], ) -> Poll<Result<usize>>

Attempt to read at most buf.len() bytes starting at offset into buf. On success returns the number of bytes read. Contents of buf are only altered on success. Reads of more than zero but fewer than buf.len() bytes do NOT indicate EOF. Reads of zero bytes only occur if buf.len() == 0 or EOF.

impl<T: Debug> Debug for Adapter<T>

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

Formats the value using the given formatter.
