Trait KeyIterable

pub trait KeyIterable<Error> {
    type Iterator<'a>: Iterator<Item = Result<&'a [u8], Error>>
       where Self: 'a;

    // Required method
    fn iterator(&self) -> Self::Iterator<'_>;
}

How to iterate over the keys returned by a search query.

Required Associated Types

type Iterator<'a>: Iterator<Item = Result<&'a [u8], Error>> where Self: 'a

The iterator returning keys by reference.

Required Methods

fn iterator(&self) -> Self::Iterator<'_>

Iterates keys by reference.

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.
