func MergeChannels ¶

func MergeChannels[T any](cs ...chan T) chan T

func Pack ¶ added in v0.4.0

func Pack(a, b int64) int64

Pack stores two ints in one. Go stores ints as 8 bytes so we store the first int in the bottom four and the second in the top four. This has a limitation of only being able to store a max value of 4294967295.

func RandomString ¶ added in v0.4.0

func RandomString(n int) string

RandomString returns a cases sensitive random string of the given length. The randonSource and character array are in the function to avoid data races. At this time its overkill to store them in a type but this can be done in the future if necessary.

func RemoveElementFromArray ¶

func RemoveElementFromArray[T any](slice []T, s int) []T

RemoveElementFromArray does just that, if an index is passed in that is larger than the slice length then the original slice is returned.

func Unpack ¶ added in v0.4.0

func Unpack(x int64) (int64, int64)

Unpack extracts two ints stored in one. 0xFFFFFFFF represents 32 bits of 1s so we AND them to x to get the first number, then we shift and AND to get the second number.
