Trait PluginFactory 

pub trait PluginFactory:
    Send
    + Sync
    + 'static {
    // Required method
    fn create(&self, config: JsonValue) -> Result<Box<dyn Plugin>>;
}

Constructs a Plugin from runtime configuration.

Required Methods

fn create(&self, config: JsonValue) -> Result<Box<dyn Plugin>>

Construct a plugin from its config section (JSON from folk.toml).

Contract: empty config must be accepted

folk-builder compiles every selected plugin into the extension unconditionally and passes {} (an empty JSON object) for any plugin whose section is absent from folk.toml. Implementations must succeed on create(json!({})) and apply sensible defaults — an absent section is not the same as a disabled plugin.

Every plugin crate should include a regression test:

#[test]
fn factory_accepts_empty_config() {
    assert!(folk_plugin_factory().create(serde_json::json!({})).is_ok());
}

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
