//! Helper macros for plugin development

/// Export a plugin with boilerplate

/// This macro generates the necessary WASM exports for your plugin.

/// ```rust,no_run

/// use std::collections::HashMap;
///
/// #[derive(Debug, Default)]
/// pub struct MyPlugin;

/// #[async_trait]
/// impl AuthPlugin for MyPlugin {
///     fn capabilities(&self) -> PluginCapabilities {
///         PluginCapabilities::default()
///     }
///
///     async fn initialize(&self, _config: &AuthPluginConfig) -> PluginCoreResult<()> {
///         Ok(())
///     }
