Crate tauri_plugin_licensemanager 

Tauri v2 plugin for licensemanager.dev: license key activation, offline tokens, background renewal, clock tampering detection and machine fingerprinting.

Register the plugin with a Builder, then reach the LicenseManager with LicensemanagerExt::license:

use std::time::Duration;
use tauri_plugin_licensemanager::{LicenseState, LicensemanagerExt};

const PUBLIC_KEY: &str = "-----BEGIN PUBLIC KEY-----\n...\n-----END PUBLIC KEY-----";

#[tauri::command]
fn export_pdf(app: tauri::AppHandle) -> Result<(), String> {
    if app.license().state() != LicenseState::Active {
        return Err("A license is required".into());
    }
    Ok(())
}

// `context` is `tauri::generate_context!()` in an app.
fn run(context: tauri::Context) {
    tauri::Builder::default()
        .plugin(
            tauri_plugin_licensemanager::Builder::new("x7Kp2QaZ", PUBLIC_KEY)
                .min_offline_duration(Duration::from_secs(14 * 86_400))
                .build(),
        )
        .invoke_handler(tauri::generate_handler![export_pdf])
        .run(context)
        .expect("error while running tauri application");
}

Structs

Builder

Configures and builds the plugin.

LicenseError

A failed license validation. Branch on code, never on message.

LicenseErrorDto

A LicenseError as JSON: { code, message, status?, latestAllowedVersion? }.

LicenseManager

The license state machine: one per app, created by the plugin and reached with LicensemanagerExt::license.

Snapshot

Everything the webview needs to render the license, in one call. Also the payload of the licensemanager://state-changed event.

Subscription

Keeps a listener registered by LicenseManager::on_state_change until dropped.

Enums

ConfigError

Invalid plugin configuration: a developer error, reported at startup.

LatestAllowedVersion

In state VERSION_NOT_ALLOWED, the latest version the license allows.

LicenseErrorCode

Error codes returned by the validate-key endpoint, plus SDK-side codes for failures that never reached a definitive server answer.

LicenseState

The license state of the app.

MachineFingerprint

User-supplied machine fingerprint source, replacing the native machine id. The value is still hashed before use.

OfflineState

Whether the last validation reached the server.

OfflineStateDto

OfflineState as JSON: { mode: "online" } or { mode: "offline", validUntil: number | null, remainingMs: number }, times in ms since the epoch.

Constants

SDK_NAME

Name of this SDK.

STATE_CHANGED_EVENT

Event emitted to every webview on each state change, with a Snapshot.

Traits

Access to the LicenseManager from an App, AppHandle, Window…
