Development Roadmap

Planned Features

• New interpolation strategies:

  • Cubic (+ extrapolation)

  • Splines (+ extrapolation?)

  • Consider others listed here: https://en.wikipedia.org/wiki/Multivariate_interpolation#Regular_grid

Breaking changes (requiring semver change)

• Plan for downstream custom strategies, may require extensive restructuring

  • This probably necessitates automating (perhaps via compile-time checks) validation of strategy/extrapolate, which is a benefit

• Extrapolate::FillValue(f64) -> Extrapolate::Fill(f64)? not sure which is 'better'

• ValidationError::StrategySelection(String) ->

  #[error("selected variant is unimplemented for Interpolator variant")]
  StrategySelection(Strategy),

• ValidationError::ExtrapolationSelection(String) ->

  #[error("selected variant is unimplemented for Interpolator variant")]
  ExtrapolateSelection(Extrapolate),

• Rename ValidationError to ValidateError?
