Struct LarkWebhookNotifier 

pub struct LarkWebhookNotifier { /* private fields */ }

HTTP client for sending cards to a Lark (Feishu) group bot webhook.

Handles HMAC-SHA256 request signing automatically on every send.

Construction

Use LarkWebhookNotifier::from_params for quick setup, or LarkWebhookNotifier::new with a LarkWebhookSettings loaded from environment variables or a TOML file:

use lark_webhook_notify::{LarkWebhookNotifier, LarkWebhookSettings};

// From env vars / config file
let settings = LarkWebhookSettings::load(None, None, None)?;
let notifier = LarkWebhookNotifier::new(settings)?;

// Or directly
let notifier = LarkWebhookNotifier::from_params("https://...", "secret")?;
