Functions

func IsEmpty

func IsEmpty(value interface{}) bool

IsEmpty checks whether given <value> empty. It returns true if <value> is in: 0, nil, false, "", len(slice/map/chan) == 0, or else it returns false.

func IsLetter

func IsLetter(b byte) bool

IsLetter checks whether the given byte b is a letter.

func IsLetterLower

func IsLetterLower(b byte) bool

IsLetterLower checks whether the given byte b is in lower case.

func IsLetterUpper

func IsLetterUpper(b byte) bool

IsLetterUpper checks whether the given byte b is in upper case.

func IsNil

func IsNil(value interface{}, traceSource ...bool) bool

IsNil checks whether given <value> is nil. Parameter <traceSource> is used for tracing to the source variable if given <value> is type of a pinter that also points to a pointer. It returns nil if the source is nil when <traceSource> is true. Note that it might use reflect feature which affects performance a little bit.

func IsNumeric

func IsNumeric(s string) bool

IsNumeric checks whether the given string s is numeric. Note that float string like "123.456" is also numeric.

func Try

func Try(tryFn func(), catchFn func(errString string)) bool

func UcFirst

func UcFirst(s string) string

UcFirst returns a copy of the string s with the first letter mapped to its upper case.
