func ArrayCast ¶

func ArrayCast[T any](source []interface{}) []T

func ArrayConvert ¶

func ArrayConvert[T any, Y any](source []Y,
	convert func(item Y) T) []T

func ArrayFilter ¶

func ArrayFilter[T any](source []T, filter func(item T) bool) []T

Return a new array list with those items from source which return true from filter function

func Average ¶

func Average(source []float64) float64

func If ¶

func If[T any](cond bool, vtrue, vfalse T) T

func IfNillable ¶ added in v0.6.9

func IfNillable[T any](cond bool, vtrueNillable func() T, vfalse T) T

In case vtrue value depends on a variable checked on condition which could be nil as params are evaluated within the If function invokation it will produce a panic error in that case we will pass the vtrue as a function which will be evaluated only if condition is met

i.e. If(foo != nil, foo.bar, "") In this case if foo is nill this will error with panic as the evaluation will try access foo which is nil

so, in this case we will use IfNillable: bar = func() { return foo.bar} IfNillable(foo != nil, bar, "")

func IfWithError ¶ added in v0.9.0

func IfWithError[T any](cond bool, vtrue, vfalse func() (T, error)) (T, error)
