Rcore: Banners

Quick guide — rcore banners

4. Compile-Time Embedded Banner

Embed version/build info using env! or option_env!:

pub const BANNER: &str = concat!(
    "rCore OS v", env!("CARGO_PKG_VERSION"),
    " (", env!("BUILD_DATE"), ")\n",
    "Commit: ", env!("GIT_HASH"),
);

Set build date in build.rs:

// build.rs
use std::time::SystemTime, UNIX_EPOCH;
fn main() {
let build_date = SystemTime::now()
.duration_since(UNIX_EPOCH)
.unwrap()
.as_secs();
println!("cargo:rustc-env=BUILD_DATE={}", build_date);
println!("cargo:rustc-env=GIT_HASH={}", get_git_hash());
}

To recap your action plan:

1. Audit your current core system. Where do users get stuck? That is where a banner belongs.
2. Design with reliability first: small file sizes, accessible colors, clear CTAs.
3. Deploy using server-side logic for personalization (e.g., show different banners to paying vs. free users).
4. Measure CTR, dismissal rate, and conversion, then iterate weekly.

Whether you are running a cloud dashboard, a financial trading terminal, or a healthcare records system, mastering rCore banners will reduce user friction, increase upgrades, and communicate critical information without the noise of traditional advertising. Set build date in build

Start small. Test one banner in one module. Watch the data. Then scale.
