Overview

Package typeutil provides utility functions for converting between different types and checking their states. It aims to provide consistent behavior across different types while remaining lightweight and dependency-free.

Functions 7

func IsZero 

1func IsZero(val any) bool
source

IsZero returns true if the value represents a "zero" or "empty" state for its type. For example:

  • Numbers: 0
  • Strings: ""
  • Slices/Maps: empty
  • nil: true
  • bool: false
  • time.Time: IsZero()
  • address: empty string

func ToBool 

1func ToBool(val any) bool
source

ToBool converts any value to a boolean based on common programming conventions. For example:

  • Numbers: 0 is false, any other number is true
  • Strings: "", "0", "false", "f", "no", "n", "off" are false, others are true
  • Slices/Maps: empty is false, non-empty is true
  • nil: always false
  • bool: direct value

func ToInterfaceSlice 

1func ToInterfaceSlice(val any) []any
source

ToInterfaceSlice converts various slice types to []any

func ToMapIntInterface 

1func ToMapIntInterface(m any) (map[int]any, error)
source

ToMapIntInterface converts a map with int keys and any value type to map[int]any

func ToMapStringInterface 

1func ToMapStringInterface(m any) (map[string]any, error)
source

ToMapStringInterface converts a map with string keys and any value type to map[string]any

func ToString 

1func ToString(val any) string
source

ToString converts any value to its string representation. It supports a wide range of Go types including:

  • Basic: string, bool
  • Numbers: int, int8-64, uint, uint8-64, float32, float64
  • Special: time.Time, address, []byte
  • Slices: []T for most basic types
  • Maps: map[string]string, map[string]any
  • Interface: types implementing String() string

Example usage:

Example
1str := typeutil.ToString(42)               // "42"
2str = typeutil.ToString([]int{1, 2})      // "[1 2]"
3str = typeutil.ToString(map[string]string{ // "map[a:1 b:2]"
4    "a": "1",
5    "b": "2",
6})

func ToStringSlice 

1func ToStringSlice(val any) []string
source

ToStringSlice converts various slice types to []string
