Struct Catalog 

pub struct Catalog { /* private fields */ }

Database catalog for names, schemas, projections, and indexes.

Performance

Cloning is O(catalog entries + string bytes).

Trait Implementations

impl Clone for Catalog

fn clone(&self) -> Catalog

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Catalog

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

Formats the value using the given formatter.

impl PartialEq for Catalog

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

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

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
