Struct io_extras::owned::OwnedReadable
source · pub struct OwnedReadable(/* private fields */);
Expand description
An owning I/O handle that implements Read
.
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
.
