1//! C0 control bytes (`0x00..=0x1f`).
2//!
3//! ## Category
4//!
5//! C0 controls are the 7-bit single-byte control characters shared with ASCII:
6//! BEL, BS, HT, LF, CR, ESC, and related communication controls.
7//!
8//! ## 7-bit escape conventions
9//!
10//! `ESC` (`0x1b`) introduces 7-bit encodings of higher-level controls such as
11//! CSI (`ESC [`), OSC (`ESC ]`), and DCS (`ESC P`). Those two-byte introducers
12//! are emitted by the writer modules for the sequence family they control; they
13//! are not represented as distinct constants here.
14//!
15//! ## Mode interaction
16//!
17//! Most C0 bytes are mode-independent, though terminals may interpret line-feed
18//! behavior according to line-feed/new-line mode ([`Mode::LINE_FEED_NEW_LINE`](crate::ansi::mode::Mode::LINE_FEED_NEW_LINE)).
