Creusot 0.14.0 adds support for partial orders in Rust proofs

devlog.creusot.rs 5 min read Editor score 6/10

Creusot 0.14.0 changes its logic for ordering specifications to support partial orders, using a strict comparison relation with irreflexivity and transitivity. This expands the kinds of Rust contracts the formal-verification tool can express.

What

Creusot 0.14.0 is a formal verification tool release for Rust that adds support for partial orders.

How

It defines partial orders with an irreflexive, transitive comparison and generates verification conditions for logic calls inside snapshots.

Why it matters

These changes let Rust engineers express and prove properties without relying on total-order assumptions or extra runtime calls.
