Functions

func FieldValueExists

func FieldValueExists[T comparable](v interface{}, name string, expectedValue T) bool

FieldValueExists uses reflection to check if any fields with the given name have the given value The is heavily adapted from https://stackoverflow.com/a/38407429

func IsInSlice

func IsInSlice(slice []string, match string) bool

IsInSlice checks if a string is in a slice.

func MapToList

func MapToList[T1 comparable, T2 any](m map[T1]T2) []T2

MapToList will change a map to a list.

func Must

func Must[T any](a T, err error) T

Must panics if the passed error is not nil

The purpose of this function is ignoring error checking when writing tests and only tests. This should not be used on production code.

Example (WithError)

// Following line will panic as there is an error
Must("abc", errors.New("an error"))

Example (WithNoError)

// Following line will not panic as there is no error
result := Must("abc", nil)

// Should print "abc"
fmt.Println(result)

func RemoveDuplicateFromSlice

func RemoveDuplicateFromSlice[T string | int](sliceList []T) []T

RemoveDuplicateFromSlice removes duplicate values from a slice.

func ToPointer

func ToPointer[T any](t T) *T

ToPointer returns a pointer to the given value.

func ToValue

func ToValue[T any](t *T) T

ToValue returns the value pointed by the given pointer.

func UpperFirstLetter

func UpperFirstLetter(str string) string

UpperFirstLetter returns the given string with the first letter in uppercase.
