Trait Layer2Data

pub trait Layer2Data: Debug + Default {
    type LoadError: Error;
    type StoreError: Error;

    // Required methods
    fn load(path: &Path) -> Result<Self, Self::LoadError>
       where Self: Sized;
    fn store(&self, path: &Path) -> Result<(), Self::StoreError>;
}

Required Associated Types

type LoadError: Error

type StoreError: Error

Required Methods

fn load(path: &Path) -> Result<Self, Self::LoadError>

where Self: Sized,

fn store(&self, path: &Path) -> Result<(), Self::StoreError>

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.
