Static #[used] asset is not included in final build (desktop)

[ronnybremer]

Problem

Declaring a static asset to be used inside of a CSS file like this

#[used]
static _FONTS: Asset = asset!(
    "/assets/fonts/webfonts/fa-solid-900.woff2",
    AssetOptions::builder()
        .with_hash_suffix(false)
        .into_asset_options()
);

dx will not export this font into the asset folder. In verbose mode during compile dx finds all other assets (which are referenced), but not the one declared above.

Pull request #4312 is merged into 0.7.0-alpha.3 but somehow the linker ignores that asset.

Steps To Reproduce

Steps to reproduce the behavior:

• declare a static asset!
• declare an asset! directly document::Stylesheet { href: asset!("/assets/css/patternfly.css", AssetOptions::builder().with_hash_suffix(false).into_asset_options()) }
• run dx serve in verbose mode
• observe the log output 16:50:20 [dev] Found asset at offset 25376800: BundledAsset { absolute_source_path: "/home/dev/test/assets/css/patternfly.css", bundled_path: "this is a placeholder path which will be replaced by the linker", options: AssetOptions { add_hash: false, variant: Unknown } }
• the same line does not get logged for the static asset

Expected behavior

The static asset should be found and included in the assets folder during the build.

Screenshots

Environment:

• Dioxus version: 0.7.0-alpha.3
• Rust version: 1.88.0
• OS info: Debian Bookworm
• App platform: desktop

@ronnybremer do you use 0.7.0-alpha.3 in Cargo.toml and also a corresponding dx binary? We were targeting web and not desktop, but I think it should work.

Or do you maybe have a strip linker setting somehow? We had this placeholder problem when the binary was stripped too much in the linker phase, as that will remove the manganis references needed for the assets.

@niclashoyer yes, I do:

## Until we publish a new version of dioxus-primitives sdk, you need to use this patch:
[patch.crates-io]
dioxus-geolocation = { git = "https://github.com/ealmloff/dioxus-std", branch = "0.7" }
dioxus-notification = { git = "https://github.com/ealmloff/dioxus-std", branch = "0.7" }
dioxus-sdk = { git = "https://github.com/ealmloff/dioxus-std", branch = "0.7" }
dioxus_storage = { git = "https://github.com/ealmloff/dioxus-std", branch = "0.7" }
dioxus-sync = { git = "https://github.com/ealmloff/dioxus-std", branch = "0.7" }
dioxus-time = { git = "https://github.com/ealmloff/dioxus-std", branch = "0.7" }
dioxus-util = { git = "https://github.com/ealmloff/dioxus-std", branch = "0.7" }
dioxus-window = { git = "https://github.com/ealmloff/dioxus-std", branch = "0.7" }

also dx is built from source:

dioxus 0.7.0-alpha.3 (was built without git repository)

[ronnybremer]

I found a workaround for development builds. Declaring the asset inside the App() like this works and the linker will find them:

    let _FONTS_AWESOME_SOLID: Asset = asset!(
        "/assets/fonts/fa-sharp-solid-900.woff2",
        AssetOptions::builder()
            .with_hash_suffix(false)
            .into_asset_options()
    );

As soon as you run dx bundle --release they will be ignored again unfortunately.
