Functions ΒΆ
func ContainsCJKChar ΒΆ
ContainsCJKChar determines whether a string contains CJK characters.
func ConvertUint64ToDecimalString ΒΆ
ConvertUint64ToDecimalString formats a uint64 to a string with a decimal point.
func DigitOf ΒΆ
DigitOf returns the n-th digit of val.
Underlying calculation is based on (val % 10^n) .
func FindDuplicates ΒΆ
func FindDuplicates[T comparable](a []T) []T
FindDuplicates returns a new slice contains items that are duplicated in a.
func Intersection ΒΆ
func Intersection[T comparable](a, b []T) []T
Intersection returns a new slice contains items that are in both a and b.
func IsASCIIPrintable ΒΆ
IsASCIIPrintable determines whether a string is printable ASCII.
func IsDecimalsPlacesValid ΒΆ
func IsInTestEnvironment ΒΆ
func IsInTestEnvironment() bool
IsInTestEnvironment determines whether the current environment is a test environment.
func IsJSONBytes ΒΆ
IsJSONBytes determines whether the bytes is JSON.
func IsStringPrintable ΒΆ
IsStringPrintable determines whether a string is printable.
func IsValidUUID ΒΆ
IsValidUUID determines whether a string is a valid UUID.
func JoinWithConverter ΒΆ
JoinWithConverter returns a string contains converted items joined with sep.
func ParseUint64FromDecimalString ΒΆ
ParseUint64FromDecimalString converts a string with a decimal point to a uint64.
func Print ΒΆ
func Print(inputs ...interface{})
Print formats the output of all incoming values in terms of field, value, type, and size.
func PrintJSON ΒΆ
func PrintJSON(inputs ...interface{})
PrintJSON formats the output of all incoming values in JSON format.
func RandomBase64Token ΒΆ
RandomBase64Token generates the URL-safe Base64 string based on the given byte length, the length is 32 by default, the length is the length of the original byte data, not the actual length of the Base64 string, the actual length is about 44 by default in the case of 32.
func RandomHashString ΒΆ
RandomHashString generates a random SHA256 string with the maximum length of 64.
func RandomInt64InRange ΒΆ
RandomInt64InRange generates a random integer in the range.
func RandomInt64String ΒΆ
RandomInt64String generates a random integer string.
func ReadFileAsBytesBuffer ΒΆ
ReadFileAsBytesBuffer reads a file and returns a bytes.Buffer.
func RelativePathOf ΒΆ
func SliceSlices ΒΆ
SliceSlices returns a new slice contains slices with maximum length each.
func Sprint ΒΆ
func Sprint(inputs ...interface{}) string
Sprint formats the output of all the fields, values, types, and sizes of the values passed in and returns the string.
NOTICE: newline control character is included.
func SprintJSON ΒΆ
func SprintJSON(inputs ...interface{}) string
SprintJSON formats the output of all incoming values in JSON format and
NOTICE: newline control character is included.
func ToMap ΒΆ
func ToMap[T any, K comparable](t []T, keyGetter func(T) K) map[K]T
ToMap converts a slice to a map with key from key getter func and pairs with value.
