Console Traits

Contains a trait which describes a console. A console is a rectangular monospaced text display, of a certain width and height. You can write Unicode text to it.

Currently we assume UNIX LF sematics - that is a sole LF implies a new line and carriage return (as distinct to Windows semantics where you would need to send a CRLF pair).

Implementors should handle the following Unicode characters specially:

• 0x08 (BS) - Backspaces one character (and erases it)
• 0x09 (TAB) - Move to next tab stop, or the end of the line if no tab stops left.
• 0x0A (LF) - Line feed.
• 0x0D (CR) - Carriage return.
• 0x7F (DEL) - Ignored.

Traits

AsciiConsole

Refinement of BaseConsole which supports 8-bit characters. Use this is you are implementing an old-fashioned ASCII console (including extended ASCII, like Code Page 850, or ISO 8859-1).

BaseConsole

Abstraction for our console. We can move the cursor around and write text to it. You should use either UnicodeConsole or AsciiConsole depending on whether you want full Unicode support (&str, char, etc), or just 8-bit characters (&[u8] and u8).

UnicodeConsole

Refinement of BaseConsole which supports Unicode characters. Use this is you are implementing a modern console with Unicode support.
