How to remove duplicate attribute declarations in Rust

[noahbald]

Hello! I'm having a bit of a struggle at the moment trying to figure out why I can't seem to remove the duplicates from Rust.

For what it's worth, I have this snippet here which I'd hope to removed the duplicates.

let style = "fill: #00f;fill: red;"

let css = match stylesheet::StyleAttribute::parse(
    &style,
    stylesheet::ParserOptions::default(),
) {
    Ok(css) => css,
    Err(e) => {
        log::warn!("failed to move styles for element: {e}");
        continue;
    }
};
let printer_options = printer::PrinterOptions {
    minify: true,
    ..printer::PrinterOptions::default()
};
let Ok(style) = css.declarations.to_css_string(printer_options) else {
    log::warn!("failed to move styles for element");
    continue;
};
log::debug!("{style}"); // "fill:#00f;fill:red"

However, it seems that using the attribute parser in the playground does seem to work.

So I'm really not sure what I'm doing wrong, whether it's a platform thing or not, so any thoughts would help!

Using 1.0.0-alpha.61 from Cargo 1.82.0 on a Linux x86_64 machine.

Read through the docs again and foudn stylesheet.minify(MinifyOptions::default()) which works
