Expand description

Capability to yield and look up Keys

Required Methods§

fn next(&mut self, internal: &Internal) -> Result<usize, KeyError>

Look up the next key in a Internal and convert to usize index.

This must be fused (like core::iter::FusedIterator).

fn finalize(&mut self) -> Result<(), KeyError>

Finalize the keys, ensure there are no more.

This must be fused.

Provided Methods§

fn chain<U>(self, other: U) -> Chain<Self, <U as IntoKeys>::IntoKeys>
where U: IntoKeys, Self: Sized,

Chain another Keys to this one.

fn track(self) -> Track<Self>
where Self: Sized,

Track depth

fn short(self) -> Short<Self>
where Self: Sized,

Track whether a leaf node is reached
