Trait DevicePlugin 

pub trait DevicePlugin:

    // Required methods
    fn kind(&self) -> &'static str;
    fn config_schema(&self) -> Schema;
    fn faults(&self) -> Vec<FaultId>;
    fn create(
        &self,
        id: DeviceId,
        config: Value,
    ) -> Result<Box<dyn Device>, ConfigError>;
}

A device type that can be instantiated from JSON config, e.g. printer-escpos.

Register plugins with Registry::register.

Required Methods

fn kind(&self) -> &'static str

The device kind this plugin creates, e.g. "printer-escpos".

fn config_schema(&self) -> Schema

JSON Schema for the config accepted by DevicePlugin::create.

fn faults(&self) -> Vec<FaultId>

Every fault a device of this kind can support, e.g. for listing faults by kind. A particular instance may support fewer, see Device::faults.

fn create( &self, id: DeviceId, config: Value, ) -> Result<Box<dyn Device>, ConfigError>

Creates a device instance. Invalid config is a ConfigError, never a panic.

Dyn Compatibility

This trait is dyn compatible.

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