Trait ev3dev_lang_rust::Findable

pub trait Findable<PortType> where
    Self: Sized,
    Self: Device,
    PortType: Port, {
    fn list() -> Ev3Result<Vec<Self>>;
    fn get(port: PortType) -> Ev3Result<Self>;
    fn find() -> Ev3Result<Self>;
}

Helper trait to create a new Device instance.

Can be automatically derived. Therefore are 3 parameters required:

• class_name: &str
• driver_name: &str
• port: dyn ev3dev_lang_rust::Motor

Example:

#[derive(Debug, Clone, Device, Findable, Motor, TachoMotor)] #[class_name = "tacho-motor"] #[driver_name = "lego-ev3-l-motor"] #[port = "crate::motors::MotorPort"] pub struct LargeMotor { driver: Driver, }

Required methods

fn list() -> Ev3Result<Vec<Self>>

Extract list of connected 'Self'

fn get(port: PortType) -> Ev3Result<Self>

Try to get a Self on the given port. Returns None if port is not used or another device is connected.

fn find() -> Ev3Result<Self>

Try to find a Self. Only returns a motor if their is exactly one connected, Error::NotFound otherwise.
