pub fn load_theme_str(text: &str, base: Theme) -> Result<Theme, ThemeError>Expand description
Load a theme from TOML text, filling anything absent from base.
Inheritance is what makes a theme file worth hand-writing: a user who wants
a different accent color writes three lines, not twenty-one. base is
typically glass_default.
§Errors
ThemeError::Syntax if the text is not TOML, ThemeError::WrongType
if a field holds the wrong kind of value, and ThemeError::BadColor if a
color is not #RRGGBB or #RRGGBBAA — each naming the field, since a
theme file has twenty-one of them and a caller cannot bisect a hand-written
one.
A section — title_bar, colors, buttons or one button within it —
that is not a table is ignored rather than refused, as upstream ignores
it: its fields are simply absent and inherit from base.
