Trait MaybeReverseIter 

pub trait MaybeReverseIter {
    type RevIfIter;

    // Required method
    fn rev_if(self, condition: bool) -> Self::RevIfIter
       where Self: Sized;
}

Adapter for reversing iterators conditionally.

Required Associated Types

type RevIfIter

Required Methods

fn rev_if(self, condition: bool) -> Self::RevIfIter

where Self: Sized,

Reverse this iterator (apply .rev()) based on some condition.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
