Trait InternalIteratorRec 

pub trait InternalIteratorRec: InternalIterator<Item = Self::Item> {
    type Item;

    // Required method
    fn try_for_each_rec<R, F>(self, f: &mut F) -> ControlFlow<R>
       where F: FnMut(<Self as InternalIteratorRec>::Item) -> ControlFlow<R>;
}

An “internal” iterator trait that supports recursively jumping between types.

Generally this isn’t implemented manually, you probably want to use the adhoc_internal_iterator_rec! macro within a function body to generate the appropriate code.

Required Associated Types

type Item

Required Methods

fn try_for_each_rec<R, F>(self, f: &mut F) -> ControlFlow<R>

where F: FnMut(<Self as InternalIteratorRec>::Item) -> ControlFlow<R>,

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.
