Struct io_extras::raw::RawReadable

source ·
pub struct RawReadable(/* private fields */);
Expand description

A non-owning unsafe I/O handle that implements Read. Read functions are considered safe, so this type requires unsafe to construct.

This doesn’t implement Into* or From* traits.

§Platform-specific behavior

On Posix-ish platforms, this reads from the handle as if it were a File. On Windows, this reads from a file-like handle as if it were a File, and from a socket-like handle as if it were a TcpStream.
