Method fill_until

libs/@local/hashql/core/src/id/vec.rs:406–414

Ensures the vector is at least long enough to contain `index`, filling with `fill` as needed. Returns a mutable reference to the element at `index`. If the vector is too short, it is extended by calling `fill` repeatedly until it contains `index`. # Examples ``` # use hashql_core::id::{IdVec, Id as _, newtype}; # newtype!(struct MyId(u32 is 0..=100)); let mut vec = IdVec:: ::new(); le

(&mut self, index: I, fill: impl FnMut() -> T)

    /// assert_eq!(vec[MyId::new(5)], 42);
    /// ```
    pub fn fill_until(&mut self, index: I, fill: impl FnMut() -> T) -> &mut T {
        let new_length = index.as_usize() + 1;

        if self.len() < new_length {
            self.raw.resize_with(new_length, fill);
        }

        &mut self[index]
    }

    /// Clears the vector, removing all elements.
