Trait Implementations

impl Clone for BrdbSchemaStructProperty

fn clone(&self) -> BrdbSchemaStructProperty

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for BrdbSchemaStructProperty

fn fmt(&self, f: &mut Formatter<'_>) -> Result
