Trait Downcast

pub trait Downcast<'b, NK, EK, T, S>
where
    NK: Key,
    EK: Key,
    T: 'b,
    S: SchemaExt<NK, EK>,
{
    // Required method
    fn downcast<'a: 'b>(&'a self) -> SchemaResult<T, NK, EK, S>;

Required Methods

fn downcast<'a: 'b>(&'a self) -> SchemaResult<T, NK, EK, S>

Cast a node or edge into a more specific type

The call will fail if the requested type is not a suptype of the current one
