Full Changelog: v0.5.0...v0.6.0

This release adds nan-handling to the argminmax project 🚀

• ArgMinMax its argminmax ignores nans (= backwards compatible)
• NanArgMinMax (only implemented for floats) its nanargminmax propagates nans (return idx of first nan)

Other changes in this release:

• feature-gate floats with the (default) "float" feature
• add proper docs 📚
• refactoring of tests, benchmarks & internal traits (making code more flexible, limiting duplicate code)

_{P.S.: Since CodSpeedHQ/codspeed-rust#1 is resolved, we removed "half" from the default-features.}

Full Changelog: v0.4.0...v0.5.0

This release improves the underlying implementation by replacing ndarray::ArrayView1 with the more flexible (and zero-dependency) &[T] slice. This new implementation enhances the library's interoperability with other array-like data types and crates.

As of now importing the ArgMinMax trait adds the .argminmax function to:

• slice (&[T])
• Vec

Using optional features, the .argminmax function can be added to:

• "ndarray" feature: ndarray::ArrayView1 & ndarray::Array1 (allows backwards compatibility)
• "arrow" feature: arrow::array::PrimitiveArray

_{P.S.: To include the amazing @CodSpeedHQ continuous performance monitoring in our CI we had to add the "half" feature as default-feature (see CodSpeedHQ/codspeed-rust#1). As soon as this issue is resolved we plan to remove again "half" from the default-features.}

What's Changed

• 🐰 add codspeed benchmarking to ci/cd by @jvdd in #15
• 🍵 use slice internally + implement for various types by @jvdd in #13
• QOL improvements by @varon in #17

New Contributors

• @varon made their first contribution in #17

Full Changelog: v0.3.1...v0.4.0

This is the latest release that uses ndarray::ArrayView1 as underlying and mandatory interface. In future releases, we will switch to using slices internally and offer optional compatibility with other data types, including ndarray::ArrayView1

_{P.S.: This release and tag were created after we had already implemented slices as the internal interface. The tag references the latest commit that includes the ndarray::ArrayView1 implementation, which corresponds to v0.3.1 of the Rust crate.}
