struct2
This repository helps to work with struct, convert map and get information about that.
This is a modified version of common struct to map libraries with cool features.
Supported tags: -, omitempty, string, ptr2, omitnested, flatten.
Convertion order is -, omitempty, string, ptr2, custom hook function, hooker interface, omitnested + flatten
Usage
go get github.com/worldline-go/struct2
Get decoder and run Map method.
type ColorGroup struct {
ID int `db:"id"`
Name string `db:"name"`
Colors []string `db:"colors"`
// custom type with implemented Hooker interface
// covertion result to time.Time
Date types.Time `db:"time"`
// unkown type but to untouch it add omitnested to keep that struct type
RGB *null.String `db:rgb,omitempty,omitnested`
}
decoder := struct2.Decoder{
TagName: "db",
}
// get map[string]interface{}
result := decoder.Map(group)
Custom decoder can be use in struct witch have struct2.Hooker interface.
Or set a slice of custom struct2.HookFunc functions in decoder.
Check documentation examples.
Tags Information
omitnested: very helpful to don’t want to touch data.
ptr2: convert pointer to the concrete value, if pointer is nil new value generating. ptr2 to effect custom hook functions and hooker interface also omitnested.
