Trait Version 

pub trait Version:
    Send
    + Sync
    + NonLocalValue
    + ValueDebug {
    // Required method
    fn id(self: Vc<Self>) -> Vc<RcStr>
       where Self: Sized;
}

Describes the current version of an object, and how to update them from an earlier version.

Important: Implementations must not contain instances of Vc! This should describe a specific version, and the value of a Vc can change due to invalidations or cache eviction.

Required Methods

fn id(self: Vc<Self>) -> Vc<RcStr>

where Self: Sized,

Get a unique identifier of the version as a string. There is no way to convert an id back to its original Version, so the original object needs to be stored somewhere.

Dyn Compatibility

This trait is dyn compatible.

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