Method map

libs/@local/hashql/core/src/module/universe.rs:183–194

Transforms the [`Realms `] into a [`Realms `] by applying a function to each value. Maps each value in this container to a new value using the provided closure. Returns a new [`Realms `] containing the mapped values for each universe. # Examples ``` use hashql_core::module::universe::{Realms, Universe}; let mut realms = Realms:: ::new(); realms.of_mut(Universe::Type) = 2; realms.of

(&self, mut closure: impl FnMut(&T) -> U)

    /// assert_eq!(*doubled.of(Universe::Value), 6);
    /// ```
    pub fn map<U>(&self, mut closure: impl FnMut(&T) -> U) -> Realms<U>
    where
        U: Default,
    {
        let mut result = Realms::<U>::new();

        for (universe, value) in self.realms() {
            *result.of_mut(universe) = closure(value);
        }

        result
    }

    /// Tests if any value in this container satisfies the predicate.
