Interval arithmetic and constraint propagation library

Modules

  • cp_solver
    Constraint propagator/solver for custom PhysicalExpr graphs.
  • interval_aritmetic
    Interval arithmetic library
  • rounding
    Floating point rounding mode utility library TODO: Remove this custom implementation and the “libc” dependency when floating-point rounding mode manipulation functions become available in Rust.
  • test_utils
    Test utilities for the interval arithmetic library
  • utils
    Utility functions for the interval arithmetic library

Structs

  • ExprIntervalGraph
    This object implements a directed acyclic expression graph (DAEG) that is used to compute ranges for expressions through interval arithmetic.
  • Interval
    This type represents an interval, which is used to calculate reliable bounds for expressions. Currently, we only support addition and subtraction, but more capabilities will be added in the future. Upper/lower bounds having NULL values indicate an unbounded side. For example; [10, 20], [10, ∞), (-∞, 100] and (-∞, ∞) are all valid intervals.
  • IntervalBound
    This type represents a single endpoint of an Interval. An endpoint can be open (does not include the endpoint) or closed (includes the endpoint).
