Module ascii 

Printable ASCII boundary constants used by the ANSI scanner.

Category

This module names the non-control byte at the start of the printable ASCII range and the DEL byte at the end of the 7-bit control area. These values are useful when classifying bytes before parsing CSI, OSC, DCS, and other escape-sequence families.

Conventions

Constants are raw byte values, not escape sequences. SP is the literal space byte (0x20); DEL is the single-byte delete control (0x7f).

Mode interaction

These bytes are independent of terminal modes. Higher-level modules such as crate::ansi::text decide whether neighboring bytes form 7-bit (ESC [) or 8-bit (0x9b) control sequences.

Constants

DEL

Delete control byte 0x7f, the last 7-bit ASCII byte. It is treated as a standalone control byte by the tokenizer.

SP

Space byte 0x20, the first printable ASCII code point and the separator often used inside CSI parameter syntax as an intermediate byte.
