Trait GhtPrefixIter

pub trait GhtPrefixIter<KeyPrefix> {
    type Item: VariadicExt;

    // Required method
    fn prefix_iter<'a>(
        &'a self,
        prefix: KeyPrefix,
    ) -> impl Iterator<Item = <Self::Item as VariadicExt>::AsRefVar<'a>>
       where Self::Item: 'a;
}

A trait to iterate through the items in a Ght based on a prefix of the schema.

Required Associated Types

type Item: VariadicExt

the schema output

Required Methods

fn prefix_iter<'a>( &'a self, prefix: KeyPrefix, ) -> impl Iterator<Item = <Self::Item as VariadicExt>::AsRefVar<'a>>

where Self::Item: 'a,

given a prefix, return an iterator through the items below

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.
