Terminal 1: run snakepipe gamestate|snakepipe render-browser
Terminal 2: run snakepipe gamestate|snakepipe render-browser
In terminal 2, you get the error:
Error: port 8080 already in use
thread 'main' panicked at library/std/src/io/stdio.rs:1021:9:
failed printing to stdout: Broken pipe (os error 32)
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace
Because
the port 8080 is already in use (normal)
Since snakepipe render-browser exit, its stdin doesn't exist anymore, so snakepipe gamestate can't write to it via its stdout
Reproduce:
Terminal 1: run
snakepipe gamestate|snakepipe render-browserTerminal 2: run
snakepipe gamestate|snakepipe render-browserIn terminal 2, you get the error:
Because
snakepipe render-browserexit, itsstdindoesn't exist anymore, sosnakepipe gamestatecan't write to it via itsstdoutMaybe rely on https://crates.io/crates/calm_io
