Structs§
- Asserts that a type implementing
std::io
traits can be used as an async type. - A wrapper around a type that implements
AsyncRead
orAsyncWrite
that convertsPending
polls toWouldBlock
errors. - Blocks on all async I/O operations and implements
std::io
traits. - Adds buffering to a reader.
- Adds buffering to a writer.

AsyncReadExt::bytes()
method. - Reader for the
AsyncReadExt::chain()
method. - Future for the
AsyncWriteExt::close()
method. - Gives an in-memory buffer a cursor for reading and writing.
