[0.4.0] 2024-01-07

Changed

  • Breaking MSRV is changed from 1.57.0 to 1.67.0.

[0.3.0] 2024-02-26

Changed

  • Breaking The only supported version of ceres-solver is 2.2 now, due to some breaking changes in the C++ API, this removes support of v2.0 and v2.1.

[0.2.2] 2024-02-26

Changed

  • Bump ceser-solver-sys to 0.2.2, which requires ceres-solver version to be between 2.0 and 2.1, because 2.2 is known to be incompatible.

[0.2.1] 2023-03-02

Changed

  • Bump ceres-solver-sys to 0.2.1 which causes turning logging off by default. We don't consider it as a breaking change, but by default you will see no output now when using "source" Cargo feature.

Removed

  • CI and "source" feature: Windows build removed. Probably it doesn't work anymore, help needed to fix it.

[0.2.0] 2023-02-11

Added

  • LossFunction::tukey().
  • solver module with customizable SolverOptions and SolverSummary containing the solution statistics.
  • Reusing of the parameter blocks in the residual blocks.
  • Make parameter block constant if you don't need to vary it.
  • Boundary conditions for the parameter blocks.
  • More documentation and examples.

Changed

  • breaking ceres-solver-sys is updated to 0.2 which gives access to more APIs of the C++ interface. It caused a lot of breaking changes in the ceres-solver crate in many ways.
  • breaking CostFunction is not public anymore, CostFunctionType is the only thing you need to know about.
  • breaking LossFunction is changed from enum to an opaque struct.
  • breaking LossFunction::tolerant_loss() renamed into LossFunction::tolerant().
  • breaking parameters module renamed into parameter_block and provides a different interface now.
  • breaking Residual blocks are now built from NllsProblem and capture it until the builder releases the problem back adding the residual block to it.
  • breaking Solution of the both problem is via ::solve(self, options: &SolverOptions) now and returns structures with the parameters and the summary.
  • More error types, they all use thiserror now.
  • Many more breaking changes.

Removed

  • loss::CustomLossFunction and loss::StockLossFunction.
  • Some more things.

[0.1.2] 2023-01-24

Added

  • CurveFitProblem1D::builder which allows to build a curve fit problem with data point uncertainties.

[0.1.1] 2023-01-20

Added

  • Cargo features for ceres-solver reflecting ceres-solver-sys #3

Fixed

  • docs.rs build #3

[0.1.0] 2023-01-19
