## Usage
|
||||
#### Defines **default** values
|
||||
**config** library supports defining a default value for structure members by using **default** keyword in structure tags
|
||||
```golang
|
||||
type Database struct {
|
||||
Username string `default:"admin"`
|
||||
Password string `default:"admin"`
|
||||
}
|
||||
```
|
||||
|
||||
After specified default value in tags, calls ```config.ParseDefault(interface{})``` to set it on structure instance, example codes as the below:
|
||||
```golang
|
||||
dbConfig := Database{}
|
||||
config.ParseDefault(&dbConfig)
|
||||
```
