# Struct tokio::io::Empty [−] [src]

    pub struct Empty { /* fields omitted */ }

An async reader which is always at EOF.

This struct is generally created by calling `empty`. Please see the documentation of `empty()` for more details.

This is an asynchronous version of `std::io::empty`.

## Trait Implementations

### `impl AsyncBufRead for Empty` [src]

#### `fn poll_fill_buf(
self: Pin<&mut Self>,
_: &mut Context<'_>
) -> Poll<Result<&[u8]>>` [src]

Attempts to return the contents of the internal buffer, filling it with more data from the inner reader if it is empty. Read more

#### `fn consume(self: Pin<&mut Self>, _: usize)` [src]

Tells this buffer that `amt` bytes have been consumed from the buffer, so they should no longer be returned in calls to `poll_read`. Read more

#### `fn poll_read(
self: Pin<&mut Self>,
_: &mut Context<'_>,
_: &mut ReadBuf<'_>
) -> Poll<Result<()>>` [src]

Attempts to read from the `AsyncRead` into `buf`. Read more

### `impl Debug for Empty` [src]

#### `fn fmt(&self, f: &mut Formatter<'_>) -> Result` [src]

Formats the value using the given formatter. Read more
