Enum PipeId 

pub enum PipeId {
    Unix(c_int),
    Windows(isize, File),
}

An identifier for a pipe. On Unix a RawFd (a c_int) is sufficient. On Windows both the file descriptor (as an isize) and a duplicated File handle is required. The duplicated file handle is created with inheritance permissions which is required for a subprocess to use the pipe. The duplicate file handle must be kept in scope until the subprocess is started, and it must then be dropped so that the child process has the only reference to it. This enables the child process to close the pipe (with an EOF).

Variants

Unix(c_int)

Windows(isize, File)
