Trait BackendFactory 

pub trait BackendFactory: Send + Sync {
    // Required methods
    fn create(&self, config: &BackendConfig) -> CanResult<Box<dyn CanBackend>>;
    fn name(&self) -> &str;
    fn version(&self) -> BackendVersion;
}

Backend factory trait.

This trait defines the factory pattern for creating backend instances. Each backend implementation should provide a factory that implements this trait.

Examples

use canlink_hal::{BackendFactory, BackendConfig};

struct MockBackendFactory;

impl BackendFactory for MockBackendFactory {
    fn create(&self, config: &BackendConfig) -> CanResult<Box<dyn CanBackend>> {
        Ok(Box::new(MockBackend::new()))
    }

    fn name(&self) -> &str {
        "mock"
    }

    fn version(&self) -> BackendVersion {
        BackendVersion::new(0, 1, 0)
    }
}

Required Methods

fn create(&self, config: &BackendConfig) -> CanResult<Box<dyn CanBackend>>

Create a new backend instance.

Arguments

• config - Backend configuration

Returns

A boxed backend instance ready for initialization.

Errors

• CanError::ConfigError - Invalid configuration
• CanError::Other - Factory-specific errors

fn name(&self) -> &str

Get the factory name.

Returns the unique identifier for this backend type.

fn version(&self) -> BackendVersion

Get the factory version.

Returns the version of the backend implementation.

Dyn Compatibility

This trait is dyn compatible.

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