Crate day_part_network 

day-part-network — a HEADLESS cross-platform network-connectivity API. No UI; any Rust code can depend on this crate and call status for a snapshot of the device’s connectivity through the platform’s NATIVE API.

if let Some(n) = day_part_network::status() {
    println!("online: {}, kind: {:?}", n.online, n.kind);
}

Platform selection is purely #[cfg(target_os)]/#[cfg(target_env)] (connectivity is an OS concern, not a widget-toolkit one): macOS and iOS share one SCNetworkReachability file, Windows uses GetNetworkConnectivityHint, Linux scans /sys/class/net, HarmonyOS the native libnet_connection.so, and Android ConnectivityManager (via a Java shim staged by day build). Platforms without a connectivity API return None.

Every field is best-effort — each OS reports a different slice of the truth. kind and expensive in particular vary per platform (macOS reachability carries no transport info, Linux infers the kind from interface names, only Android/HarmonyOS report meteredness); see the per-field docs and docs/network.md for the honest per-platform matrix.

Structs

NetworkStatus

A snapshot of the device’s network connectivity.

Enums

NetworkKind

The transport class of the active network connection. Best-effort — not every platform can distinguish these (see NetworkStatus::kind).

Functions

status

Read a connectivity snapshot via the platform’s native API. Returns None when there is no connectivity API on the platform (or the reading failed) — distinct from a successful reading that says offline (Some with online: false).
