rmux_core/terminal_screen.rs
1//! Public live-terminal screen facade.

3//! This module exposes the server-facing screen wrapper while keeping the
4//! parser implementation inside the crate-private `terminal` module.

14/// `TerminalScreen` is the public core facade that server code uses to feed
15/// raw PTY bytes and inspect structured screen cells. The parser itself stays
16/// hidden behind the crate-private terminal module, so SDK/protocol code can
17/// depend on screen-cell semantics without coupling to parser internals.
