Detailed Description

A stream referring to stdin/stdout/stderr. Should be created using one of the static member functions, each of which creates a TTY stream referring to the respective standard stream.

Note: these must be TTYs; input/output redirection may cause failures in libuv. Normal files are not yet implemented.
