Trait PluginFactory 

pub trait PluginFactory:
    Default
    + Plugin
    + Sized {
    // Provided methods
    fn create(config: &PluginConfig) -> PluginResult<Self> { ... }
    fn create_configured(_config: &PluginConfig) -> PluginResult<Self> { ... }
}

Factory trait for creating plugins with optional configuration.

The framework calls create() which handles the null-config case automatically by falling back to Default::default().

Plugin authors only need to override create_configured() if they want to use config.data for initialization.

Example

use rustbridge_core::prelude::*;

struct MyPlugin {
    cache_size: usize,
}

impl Default for MyPlugin {
    fn default() -> Self {
        Self { cache_size: 100 }
    }
}

impl PluginFactory for MyPlugin {
    fn create_configured(config: &PluginConfig) -> PluginResult<Self> {
        let size = config.get::<usize>("cache_size").unwrap_or(100);
        Ok(Self { cache_size: size })
    }
}

Provided Methods

fn create(config: &PluginConfig) -> PluginResult<Self>

Create a plugin instance. Called by the framework.

Default implementation: uses Default when config.data is null, otherwise calls create_configured().

fn create_configured(_config: &PluginConfig) -> PluginResult<Self>

Create a plugin with non-null config.data.

Override this to parse and use configuration data. Default implementation ignores config and uses Default.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
