CvlrInvarSpec

cvlr_spec::spec

Struct CvlrInvarSpec 

Source 
pub struct CvlrInvarSpec<A, B>(/* private fields */);
Expand description

A specification for invariants that must hold before and after operations.

This type represents a specification where:

  • An assumption (additional precondition) is assumed before the operation
  • An invariant must hold both before and after the operation

The invariant is assumed in the pre-state and asserted in the post-state.
