Simple Crate For Converting Hashmaps To Structs

Convert HashMap<String, String> values directly into structs, with optional type conversion per field.

Provides one main trait and derive macro, named Map2Struct.

Example

use std::collections::HashMap;
use map2struct::Map2Struct;

#[derive(Map2Struct)]
struct Person {
    name: String,
    age: u32,
}

let mut map = HashMap::new();
map.insert("name".to_string(), "John".to_string());
map.insert("age".to_string(), "30".to_string());
let person = Person::from_map(map).expect("Parsing failed");
assert_eq!(person.name, "John");
assert_eq!(person.age, 30);

Fields are parsed using the .parse method of String values.

The following validations steps are performed:

1. Check if all fields are present
2. Check that no additional fields are present
3. Check type conversions
