maps

Overview ¶

Package maps provides utility functions for working with maps and structs. It includes functions for converting between maps and structs, as well as retrieving nested values from maps using dot notation.

This package is particularly useful when dealing with dynamic data structures or when working with configuration data that needs to be converted between different formats.

Key features: - Map2Struct: Converts a map to a struct using reflection - Get: Retrieves nested values from maps using dot notation - Support for weakly typed input when converting maps to structs - Handling of time.Duration conversions from string representations

Usage example:

input := map[string]interface{}{
	"name": "John Doe",
	"age":  30,
	"address": map[string]interface{}{
		"street": "123 Main St",
		"city":   "Anytown",
	},
}

// Retrieve a nested value
city := maps.Get(input, "address.city")

// Convert map to struct
type Person struct {
	Name    string
	Age     int
	Address struct {
		Street string
		City   string
	}
}
var person Person
err := maps.Map2Struct(input, &person)
