Function mut_set 

pub fn mut_set<Root, Value>(
    keypath: KeyPaths<Root, Value>,
    value: Value,
) -> impl FnMut(&mut Root)
where
    Root: Clone + 'static,
    Value: Clone + 'static,

Produces a value-mutable setter function for a given key path and new value. Equivalent to Swift’s mut<Root, Value>(_ keyPath: WritableKeyPath<Root, Value>, _ value: Value) -> (inout Root) -> Void

Examples

use rust_overture::keypaths::mut_set;
use key_paths_core::KeyPaths;

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

let age_keypath = KeyPaths::writable(|person: &mut Person| &mut person.age);
let mut set_age_25 = mut_set(age_keypath, 25);
let mut person = Person { name: "Alice".to_string(), age: 30 };
set_age_25(&mut person);
assert_eq!(person.age, 25);
