Struct TableDefinition

pub struct TableDefinition { /* private fields */ }

Available on crate feature duckdb only.

A table definition, which includes the table name, schema, constraints, and indexes. This is used to store the definition of a table for a dataset, and can be re-used to create one or more tables (like internal data tables).

Implementations

impl TableDefinition

pub fn name(&self) -> &RelationName

pub fn has_table(&self, tx: &Transaction<'_>) -> Result<bool, Error>

Returns true if this table definition has a base table matching the exact RelationName of the definition

Errors

If the transaction fails to query for whether the table exists.

pub fn list_internal_tables( &self, tx: &Transaction<'_>, ) -> Result<Vec<(RelationName, u64)>, Error>

List all internal tables related to this table definition.

Errors

Returns an error if the internal tables cannot be listed.

Trait Implementations

impl Clone for TableDefinition

fn clone(&self) -> TableDefinition

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TableDefinition

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

Formats the value using the given formatter.

impl PartialEq for TableDefinition

fn eq(&self, other: &TableDefinition) -> 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.
