util

func AsMap ¶

func AsMap[T any, K comparable](slice []T, keyGetter Mapper[T, K]) map[K]T

func AsSet ¶

func AsSet[T any, K comparable](slice []T, keyGetter Mapper[T, K]) map[K]bool

func ByteCountSI ¶

func ByteCountSI(b int64) string

func Chunk ¶

func Chunk[T any](slice []T, size int) [][]T

Chunk batches []T into [][]T in groups of size. The final chunk of []T will be smaller than size if the input slice cannot be chunked evenly. It does not make any copies of slice elements.

As an example, take a slice of 5 integers and create chunks of 2 integers each (the final value creates a short chunk):

slices.Chunk([]int{1, 2, 3, 4, 5}, 2) = [][]int{{1, 2}, {3, 4}, {5}}

func Copy ¶

func Copy[T any](t T) T

func GroupByProperty[T any, K comparable](items []T, getProperty func(T) K) map[K][]T

func Keys ¶

func Keys[K comparable, V any](m map[K]V) []K

func LogSymbol ¶
