Required methods

fn rootify(
    &mut self,
    key: &<Self::Construct as Construct>::Value
) -> Result<(), Self::Error>

Rootify a key.

fn unrootify(
    &mut self,
    key: &<Self::Construct as Construct>::Value
) -> Result<(), Self::Error>

Unrootify a key.

fn insert(
    &mut self,
    key: <Self::Construct as Construct>::Value,
    value: (<Self::Construct as Construct>::Value, <Self::Construct as Construct>::Value)
) -> Result<(), Self::Error>
