Trait lock_ext::LockExt

pub trait LockExt {
    type Value;
    pub fn with<Scope, Out>(&self, scope: Scope) -> Out
    where
        Scope: FnOnce(&mut Self::Value) -> Out;
}

Extend functionality of std::sync::Mutex

Example

let lock = Mutex::new(Vec::new());
lock.with(|value| value.push("hello"));
let hello = lock.with(|value| value.get(0).unwrap().to_owned());
