Variables ¶
var ( // Priority tags for Map*/Struct* functions. // Note, the "gconv", "param", "params" tags are used by old version of package. // It is strongly recommended using short tag "c" or "p" instead in the future. StructTagPriority = []string{"gconv", "param", "params", "c", "p", "json"} )
Functions ¶
func Bool ¶
func Bool(any interface{}) bool
Bool converts <i> to bool. It returns false if <i> is: false, "", 0, "false", "off", "no", empty slice/map.
func Convert ¶
func Convert(any interface{}, t string, params ...interface{}) interface{}
Convert converts the variable <i> to the type <t>, the type <t> is specified by string. The optional parameter <params> is used for additional necessary parameter for this conversion. It supports common types conversion as its conversion based on type name string.
func Duration ¶
Duration converts <i> to time.Duration. If <i> is string, then it uses time.ParseDuration to convert it. If <i> is numeric, then it converts <i> as nanoseconds.
func GTime ¶
GTime converts <i> to *gtime.Time. The parameter <format> can be used to specify the format of <i>. If no <format> given, it converts <i> using gtime.NewFromTimeStamp if <i> is numeric, or using gtime.StrToTime if <i> is string.
func Interfaces ¶
func Interfaces(any interface{}) []interface{}
Interfaces converts <i> to []interface{}.
func Map ¶
Map converts any variable <value> to map[string]interface{}. If the parameter <value> is not a map/struct/*struct type, then the conversion will fail and returns nil.
If <value> is a struct/*struct object, the second parameter <tags> specifies the most priority tags that will be detected, otherwise it detects the tags in order of: gconv, json, field name.
func MapDeep ¶
MapDeep does Map function recursively, which means if the attribute of <value> is also a struct/*struct, calls Map function on this attribute converting it to a map[string]interface{} type variable. Also see Map.
func MapStrStr ¶
MapStrStr converts <value> to map[string]string. Note that there might be data copy for this map type converting.
func MapStrStrDeep ¶
MapStrStrDeep converts <value> to map[string]string recursively. Note that there might be data copy for this map type converting.
func MapToMap ¶
MapToMap converts any map type variable <params> to another map type variable <pointer> using reflect. See doMapToMap.
func MapToMapDeep ¶
MapToMapDeep converts any map type variable <params> to another map type variable <pointer> using reflect recursively. Deprecated, use MapToMap instead.
func MapToMaps ¶
MapToMaps converts any map type variable <params> to another map type variable <pointer>. See doMapToMaps.
func MapToMapsDeep ¶
MapToMapsDeep converts any map type variable <params> to another map type variable <pointer> recursively. Deprecated, use MapToMaps instead.
func Maps ¶
Maps converts <i> to []map[string]interface{}. Note that it automatically checks and converts json string to []map if <value> is string/[]byte.
func MapsDeep ¶
MapsDeep converts <i> to []map[string]interface{} recursively.
TODO completely implement the recursive converting for all types.
func Scan ¶
Scan automatically calls Struct or Structs function according to the type of parameter <pointer> to implement the converting. It calls function Struct if <pointer> is type of *struct/**struct to do the converting. It calls function Structs if <pointer> is type of *[]struct/*[]*struct to do the converting.
func ScanDeep ¶
ScanDeep automatically calls StructDeep or StructsDeep function according to the type of parameter <pointer> to implement the converting.. It calls function StructDeep if <pointer> is type of *struct/**struct to do the converting. It calls function StructsDeep if <pointer> is type of *[]struct/*[]*struct to do the converting. Deprecated, use Scan instead.
func SliceMapDeep ¶
func SliceMapDeep(any interface{}) []map[string]interface{}
SliceMapDeep is alias of MapsDeep.
func SliceStruct ¶
SliceStruct is alias of Structs.
func SliceStructDeep ¶
func SliceStructDeep(params interface{}, pointer interface{}, mapping ...map[string]string) (err error)
SliceStructDeep is alias of StructsDeep. Deprecated, use SliceStruct instead.
func String ¶
func String(any interface{}) string
String converts <i> to string. It's most common used converting function.
func Struct ¶
Struct maps the params key-value pairs to the corresponding struct object's attributes. The third parameter <mapping> is unnecessary, indicating the mapping rules between the custom key name and the attribute name(case sensitive).
Note:
- The <params> can be any type of map/struct, usually a map.
- The <pointer> should be type of *struct/**struct, which is a pointer to struct object or struct pointer.
- Only the public attributes of struct object can be mapped.
- If <params> is a map, the key of the map <params> can be lowercase. It will automatically convert the first letter of the key to uppercase in mapping procedure to do the matching. It ignores the map key, if it does not match.
func StructDeep ¶
StructDeep do Struct function recursively. Deprecated, use Struct instead.
func StructsDeep ¶
StructsDeep converts any slice to given struct slice recursively. Deprecated, use Structs instead.
func UnsafeBytesToStr ¶
UnsafeBytesToStr converts []byte to string without memory copy. Note that, if you completely sure you will never use <b> variable in the feature, you can use this unsafe function to implement type conversion in high performance.
func UnsafeStrToBytes ¶
UnsafeStrToBytes converts string to []byte without memory copy. Note that, if you completely sure you will never use <s> variable in the feature, you can use this unsafe function to implement type conversion in high performance.
