class Erlang::ETF::Pid

| 1 | N | 4 | 4 | 1 | | — | —- | — | —— | ——– | | 103 | Node | ID | Serial | Creation |

Encode a process identifier object (obtained from [`spawn/3`] or friends). The `ID` and `Creation` fields works just like in [`REFERENCE_EXT`], while the `Serial` field is used to improve safety. In `ID`, only 15 bits are significant; the rest should be 0.

(see [`PID_EXT`])
