Trait FlatMapInPlace 

Source 
pub trait FlatMapInPlace<T> {
    // Required method
    fn flat_map_in_place<F, I>(&mut self, f: F)
       where F: FnMut(T) -> I,
             I: IntoIterator<Item = T>;
}

Required Methods§

Source

fn flat_map_in_place<F, I>(&mut self, f: F)
where F: FnMut(T) -> I, I: IntoIterator<Item = T>,

f turns each element into 0..many elements. This function will consume the existing elements in a vec-like structure and replace them with any number of new elements — fewer, more, or the same number — as efficiently as possible.

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
