javy-plugin-api 6.0.0

/// Provides default implementations for required methods a Javy plugin.
///
/// # Arguments
///
/// * `namespace` - The name of the module that will be used for function
///   imports in dynamically linked modules generated with this plugin.
/// * `component` - A struct.
/// * `config` - A function that will return a [`javy::Config`] to configure
///   the [`javy::Runtime`].
/// * `modify_runtime` - A function that can add modify the [`javy::Runtime`].
///   For example, by adding additional methods for use by JavaScript.
///
/// # Examples
///
/// ```ignore
/// use javy_plugin_api::{javy::{Config, Runtime}, javy_plugin};
///
/// struct Component;
///
/// javy_plugin!("my-import-namespace", Component, config, modify_runtime);
///
/// fn config() -> Config {
///     Config::default()
/// }
///
/// fn modify_runtime(runtime: Runtime) -> Runtime {
///     runtime
/// }
