utils

utils

Small generic utilities used across teahub packages.

What it does

• IsStruct: Reports whether a reflect.Type is a struct (e.g. for logging or validation).
• MergeArrays: Merges multiple slices of the same type into one.
• GenerateRandomString: Returns a random alphanumeric string of a given length.
• GenerateRandomIntInRange: Returns a random integer in [min, max] (inclusive).

No external dependencies beyond the standard library.

Installation

go get github.com/teathedev/pkg/utils

Usage

import (
	"reflect"
	"github.com/teathedev/pkg/utils"
)

// Type check
func handle(v any) {
	t := reflect.TypeOf(v)
	if utils.IsStruct(t) {
		// v is a struct type
	}
}

// Merge slices
a, b, c := []int{1, 2}, []int{3}, []int{4, 5}
merged := utils.MergeArrays(a, b, c) // []int{1, 2, 3, 4, 5}

// Random string (A–Z, a–z, 0–9)
s := utils.GenerateRandomString(16) // e.g. "x7Kp2mNq9vLw4Rc1"

// Random int in range [min, max] inclusive
n := utils.GenerateRandomIntInRange(1, 100)

API

Function	Description
IsStruct(t reflect.Type) bool	Returns true if t.Kind() == reflect.Struct.
MergeArrays[T any](arrays ...[]T) []T	Concatenates all given slices into one.
GenerateRandomString(length int) string	Random alphanumeric string (A–Z, a–z, 0–9) of length length.
GenerateRandomIntInRange(min, max int) int	Random int in [min, max] inclusive.
