Trait Implementations

impl Clone for ColumnCatalog

fn clone(&self) -> ColumnCatalog

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ColumnCatalog

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

Formats the value using the given formatter.

impl From<ColumnCatalog> for ColumnCatalog

impl PartialEq for ColumnCatalog

fn eq(&self, other: &ColumnCatalog) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool
