Functions ¶
func ParseSettingTagToMap ¶
ParseSettingTag 适用于子tag为多配置项
type example struct {
db string `specifyTagName:"config:db;default:postgres`
}
default sep ;
func ParseSettingTagToStruct ¶
func SubTagLookup ¶
Types ¶
type SettingTag ¶
type SettingTag string
type Tag ¶
type Tag struct {
Index int
// Key is the tag key, such as json, xml, etc..
// i.e: `json:"foo,omitempty". Here key is: "json"
Key string
// Name is a part of the value
// i.e: `json:"foo,omitempty". Here name is: "foo"
Value string
// Options are the tag options, such as omitempty, required, etc..
// i.e: `json:"foo,omitempty". Here options is: ["omitempty"]
Options []string
}
Tag defines a single struct's string literal tag
func (*Tag) AddOptions ¶
AddOptions adds the given option for the given key. If the option already exists it doesn't add it again.
func (*Tag) DeleteOptions ¶
DeleteOptions deletes the given options for the given key
type Tags ¶
type Tags struct {
// contains filtered or unexported fields
}
Tags represent a set of tags from a single struct field
func (*Tags) Get ¶
Get returns the tag associated with the given key. If the key is present in the tag the value (which may be empty) is returned. Otherwise the returned value will be the empty string. The ok return value reports whether the tag exists or not (which the return value is nil).
func (*Tags) Keys ¶
Tags returns a Slice of tags. The order is the original tag order unless it was changed.
