Source

pub trait MessageFilter: Send + Sync {
    // Required method
    fn matches(&self, message: &CanMessage) -> bool;

    // Provided methods
    fn priority(&self) -> u32 { ... }
    fn is_hardware(&self) -> bool { ... }
}

Message filter trait

All filter implementations must implement this trait. Filters can be either hardware-accelerated or software-based.

§Thread Safety

Implementations must be Send + Sync to allow use across threads.

§Example

use canlink_hal::filter::MessageFilter;
use canlink_hal::message::CanMessage;

struct MyFilter {
    target_id: u32,
}

impl MessageFilter for MyFilter {
    fn matches(&self, message: &CanMessage) -> bool {
        message.id() == self.target_id
    }
}
