pub struct Empty { /* private fields */ }
Expand description

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§

Attempts to return the contents of the internal buffer, filling it with more data from the inner reader if it is empty. Read more
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
Attempts to read from the AsyncRead into buf. Read more
Formats the value using the given formatter. Read more
