Struct io_extras::borrowed::BorrowedWriteable

source ·
pub struct BorrowedWriteable<'a> { /* private fields */ }
Expand description

An owning I/O handle that implements Write.

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

§Platform-specific behavior

On Posix-ish platforms, this writes to the handle as if it were a [File]. On Windows, this writes to a file-like handle as if it were a [File], and to a socket-like handle as if it were a TcpStream.
