Struct Theme 

pub struct Theme {
    pub name: String,
    pub colors: ColorScheme,
    pub fonts: FontScheme,
}

A presentation’s customizable color/font theme (ppt/theme/theme1.xml’s own <a:clrScheme>/<a:fontScheme>).

Deliberately mirrors word_ooxml::Theme/ColorScheme/FontScheme by name and shape, not by crate dependency — this workspace’s established posture for a shared real-world concept with no shared crate backing it (see PictureFormat’s own doc comment for the same reasoning). Unlike word_ooxml::Theme (genuinely optional — word/theme/theme1.xml is only written when Document.theme is set), a PowerPoint theme part is mandatory: Presentation.theme: None still always produces a full theme1.xml, just with Theme::office_default’s colors/fonts rather than a caller-supplied palette — see Presentation’s own doc comment.

Real PowerPoint files can and do carry more than one distinct theme (a real fixture has both theme1.xml and theme2.xml, the latter the notes master’s own); this crate, like word-ooxml, still only exposes a single customizable theme for the slide master (the notes master’s own separate theme part stays fixed at Theme::office_default’s content regardless).

fmtScheme (CT_BaseStyles requires it alongside clrScheme/ fontScheme) stays a fixed, non-configurable copy of Office’s own built-in default, same scope limit as word_ooxml::Theme’s own fmtScheme — irrelevant to word-ooxml there, but genuinely relevant to a slide’s shapes here; still out of scope.

Fields

name: String

The theme’s name (<a:theme name="..">), also reused unchanged as the nested <a:clrScheme>/<a:fontScheme> elements’ own name attribute, same convention as word_ooxml::Theme.

colors: ColorScheme

fonts: FontScheme

Implementations

impl Theme

pub fn office_default() -> Theme

Office’s own built-in default theme (“Office”: Calibri Light/ Calibri, the classic blue-accented palette) — byte-for-byte the same colors/fonts this crate’s writer has always produced as its fixed theme, now expressed as data instead of a hardcoded XML literal.
