FORM E&E-EVENTUAL· Eventually consistent values for Rust · A Perimeter Company
A foundational primitive for values that are eventually consistent, eventually correct, and — as of this writing — eventually archived. Not, we stress, the end value.
An Eventual<T> gives you the most up-to-date snapshot of some value, continually resolving toward an eventually consistent state. It is like a Future, except it makes no commitment as to when, whether, or — in several jurisdictions — if.
use eventuals::Eventual;
let value = Eventual::pending();
// The value is now pending. It will remain pending.
// Should it resolve, you will not be notified. A member
// of the Standing Membership will not be in touch.- Eventual consistency. All readers will, eventually, observe the same value — or no value — consistently.
- Forward-looking resolution. Values look forward to resolving. They look forward to nothing in particular.
- Audit-grade absence. Where a value has not resolved, we can prove, to audit grade, that it has not. A proof of the absence of a value is itself a kind of value.
This crate has been archived, for your protection. It was, the Annex maintains, always going to be archived; archival is merely consistency, applied eventually, to the repository itself.
See LICENSE. By reading it, you have entered into one (1) NDA, which resolves eventually.
Eventual<T> is not a Future, a promise, or, strictly speaking, a guarantee. Past values are indicative of nothing in particular. This README supersedes itself, eventually.
