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
.
