simplefeatures v0.34.0 Release Notes

  • 2021-11-02

    🚀 Special thanks to Albert Teoh for contributing to this release.

    • 💥 Breaking change: Renames the AsFoo methods of the Geometry type to MustAsFoo (where Foo is a concrete geometry type such as Point). This follows the go convention that methods and functions prefixed with Must may panic if preconditions are not met. Note that there's no change in behaviour here, it's simply a rename (these methods previously panicked). Users may resolve this breaking change by just updating the names of any AsFoo methods they are calling to MustAsFoo.

    • 💥 Breaking change: Adds new methods named AsFoo to the Geometry type. These methods have the signature AsFoo() (Foo, bool). The boolean return value indicates if the conversion was successful or not. These methods are useful because they allow concrete geometries to be extracted from a Geometry value, with the concrete type for the Is and As call only specified once. Users now just have to call AsFoo, and can then check the flag. This helps to eliminate the class of bugs there the type specified with IsFoo erroneously differs from the type specified by AsFoo.
