Parsing Results Examples

Under the hood Zog follows the Parsing Execution Structure and does a bunch of things under the hood to make sure your data is parsed correctly. Such as checking for zero values, coercing types, etc...

Some of this might not be obvious so here is a summary table that breaksdown expected results of calling schema.Parse() on various inputs:

Schema Type	Data	Dest	Required Error (Zero Value)	Coercion Error
Bool()	true	true	no	no
Bool()	false	false	no	no
Bool()	nil	false	yes	yes
Bool()	""	false	yes	yes
Bool()	" "	false	yes	yes
Bool()	on	true	no	no
Bool()	off	false	no	no
Bool()	["true", "t", "T", "True", "TRUE"]	true	no	no
Bool()	["false", "f", "F", "FALSE", "False"]	false	no	no
Bool()	test	false	no	yes
Bool()	1	true	no	no
Bool()	0	false	no	no
Bool()	123	false	no	yes
String()	""	""	yes	no
String()	" "	""	yes	no
String()	nil	""	yes	yes
String()	any value	fmt.Sprintf("%v", value)	no	no
Int()	0	0	no	no
Int()	10	10	no	no
Int()	nil	0	yes	yes
Int()	""	0	yes	yes
Int()	" "	0	yes	yes
Int()	any string	strconv.Atoi(str)	no	depends
Int()	6.29	6	no	no
Int()	true	1	no	no
Int()	false	0	no	no
Float()	1.21	1.21	no	no
Float()	0	0	no	no
Float()	nil	0	yes	yes
Float()	""	0	yes	yes
Float()	" "	0	yes	yes
Float()	any string	strconv.ParseFloat(str)	no	depends
Float()	1	1	no	no
Time()	time.Time{}	time.Time{}	no	no
Time()	time.Now()	time.Now()	no	no
Time()	nil	time.Time{}	yes	yes
Time()	""	time.Time{}	yes	yes
Time()	" "	time.Time{}	yes	yes
Time()	unix_timestamp_ms	time.Unix(unix, 0)	no	no
Time()	any string	time.Parse(format, str)	no	depends
Slice()	[1]	[1]	no	no
Slice()	[]	[]	no	no
Slice()	nil	[null]	yes	no (error will show in the appropriate schema if any)
Slice()	""	[""]	yes	no (error will show in the appropriate schema if any)
Slice()	" "	[" "]	yes	no (error will show in the appropriate schema if any)
Slice()	any_value	[value]	depends	no (error will show in the appropriate schema if any)
