Trait Persist

pub trait Persist<'a>
where
    Self: Sized,
{
    type State;
    type ConstructorArgs;
    type Error;

    // Required methods
    fn save(&self) -> Self::State;
    fn restore(
        constructor_args: Self::ConstructorArgs,
        state: &Self::State,
    ) -> Result<Self, Self::Error>;
}

An abstract interface for saving/restoring a component using a specific state.

Required Associated Types

type State

The type of the object representing the state of the component.

type ConstructorArgs

The type of the object holding the constructor arguments.

type Error

The type of the error that can occur while constructing the object.

Required Methods

fn save(&self) -> Self::State

Returns the current state of the component.

fn restore( constructor_args: Self::ConstructorArgs, state: &Self::State, ) -> Result<Self, Self::Error>

Constructs a component from a specified state.

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.
