Struct Capabilities

pub struct Capabilities {
    pub cyd: CydWasm,
    pub button: ButtonWasm,
    pub clock_sync: ClockSyncWasm,
    pub wifi_simulator: WifiSimulatorWasm,
    pub dns_simulator: DnsSimulatorWasm,
}

Expand description

Complete capability container supplied to each application run.

A launcher receives this value from start, selects focused capabilities, and returns a Command. The compiled browser-shell example on crate::wasm::cyd_web reads every field.

async fn inner_main(
    mut capabilities: cyd_web::Capabilities,
) -> Result<cyd_web::Command, Infallible> {
    capabilities.clock_sync.show();
    assert_eq!(capabilities.cyd.display().screen_size().width, 320);
    Ok(cyd_web::Command::Stop)
}

Fields§

§cyd: CydWasm

§button: ButtonWasm

BOOT-button capability.

§clock_sync: ClockSyncWasm

Browser-backed clock capability.

§wifi_simulator: WifiSimulatorWasm

Simulated Wi-Fi capability.

§dns_simulator: DnsSimulatorWasm

Deterministic simulated DNS capability.
