Could you build this?
No Developing a performant shell autocomplete daemon in Rust requires low-level systems programming, terminal pseudo-terminal (PTY) handling, POSIX signal handling, and deep shell-specific internals across Zsh, Bash, and Fish.
What it would actually take: This requires systems-level Rust programming interfacing directly with Unix TTY/termios APIs and shell hooks to render sub-10ms UI overlays inside terminal emulators. The developer must parse shell ASTs, manage IPC between background daemons and running shells, and handle edge cases across OS kernels without interfering with user command execution.
