Module export 

Multi-format export backends (E012 US2 — Phase 7).

Public types: export::ExportFormat, export::write_export. Each individual backend is gated behind its output-<format> leaf: HTML5 (output-html), mIRC ^C codes (output-irc), SVG 1.1 (output-svg). The ANSI sub-formats reuse ColorDepth from color_depth for SGR emission. Multi-format export backends (E012 US2 — FR-005, Phase 7).

Backends

Each backend is gated behind a distinct output-<format> Cargo leaf per ADR-0006:

Format	Leaf	Module
HTML5	output-html	[html]
mIRC ^C	output-irc	[irc]
SVG 1.1	output-svg	[svg]
ANSI 16	(always)	(renders via crate::color_depth)
ANSI 256	color-256	(renders via crate::color_depth)
ANSI 24bit	color-truecolor	(renders via crate::color_depth)

Dispatch

[write_export] receives a crate::filter::RenderGrid and an [ExportFormat] and dispatches to the appropriate backend, returning a Vec<u8> with the encoded bytes. When the requested format’s leaf is disabled at compile time, FigletError::UnsupportedExportFormat is returned with the full list of available formats so the CLI can produce a useful diagnostic per FR-016.

Security

• HTML/SVG: 4-char escape applied to every text-content and double- quoted-attribute byte per AD-004 + HINT-004 — see [html] module docs for the exact set + reasoning.
• IRC: ASCII C0/C1 non-printable bytes stripped per FR-015; UTF-8 continuation bytes preserved per spec Edge Cases — see [irc] module docs.
• SVG: NO <script>, <foreignObject>, xlink:href, <image href=...>, <use xlink:href=...> emission. Inline style="..." IS emitted but contains only typed numeric #RRGGBB values — no user bytes ever flow into a style value per spec Edge Cases.
