Overview

Package mapstrstr contains utilities for transforming map[string]string objects into metricbeat events. For example, given this input object:

input := map[string]interface{}{
	"testString":     "hello",
	"testInt":        "42",
	"testBool":       "true",
	"testFloat":      "42.1",
	"testObjString":  "hello, object",
}

And the requirement to transform it into this one:

common.MapStr{
	"test_string": "hello",
	"test_int":    int64(42),
	"test_bool":   true,
	"test_float":  42.1,
	"test_obj": common.MapStr{
		"test_obj_string": "hello, object",
	},
}

It can be done with the following code:

schema := s.Schema{
	"test_string": Str("testString"),
	"test_int":    Int("testInt"),
	"test_bool":   Bool("testBool"),
	"test_float":  Float("testFloat"),
	"test_obj": s.Object{
		"test_obj_string": Str("testObjString"),
	},
}
schema.Apply(input)

Note that this allows parsing, renaming of fields and restructuring the result object.
