Functions

func Cast

func Cast[M ~map[K]V, K comparable, V any](input M) map[K]any

Cast turns a map[K]V to a map[K]any, so values will downcast to 'any' type.

func Inverse

func Inverse[K, V comparable](input map[K]V) map[V]K

Inverse switches the values to keys and the keys to values.

func Keys

func Keys[M ~map[K]V, K comparable, V any](input M) []K

Keys returns the keys of the map m. The keys will be an indeterminate order.

func MergeJSON

func MergeJSON(x1, x2 []byte, orderBy func(output map[string]any) any) ([]byte, error)

MergeJSON merges the two JSON byte slices. It returns an error if x1 or x2 cannot be JSON-unmarshalled, or the merged JSON is invalid.

Optionally, an orderBy function can be provided to alter the key order in the resulting JSON

func PrettyPrintJSON

func PrettyPrintJSON(content []byte, name string) []byte

func ReadFile

func ReadFile(filePath string) string

ReadFile read a plain or gzipped file and return contents as string

func SurfaceArea

func SurfaceArea(bbox *geom.Bounds) float64
