Struct CatalogTable 

pub struct CatalogTable { /* private fields */ }

One table registered in a Catalog: a (catalog?, schema?, name) identity plus its column names.

name is mandatory; schema and catalog are optional — a bare table (e.g. from unqualified DDL) has neither, and engines without a catalog layer omit the catalog. An omitted segment matches any query value there (right-anchored, the same wildcard rule a query reference gets for its own omitted qualifiers), so a schema-less users matches both a bare users and a qualified public.users. Identifiers are stored verbatim; a present segment compares exactly (folding only under case-insensitive dialects — see the module docs). columns may be empty when the table is known but its columns aren’t.

Implementations

impl CatalogTable

pub fn new(schema: impl Into<String>, name: impl Into<String>) -> Self

A table identified by schema.name, with no columns yet and no catalog segment. Add columns with Self::columns and a catalog with Self::catalog.

pub fn unqualified(name: impl Into<String>) -> Self

A table with no schema (e.g. from unqualified DDL). The omitted schema is a wildcard, so it matches a query by name alone — bare users and qualified public.users both match. Add columns with Self::columns.

pub fn catalog(self, catalog: impl Into<String>) -> Self

Set the catalog segment (for engines with a catalog layer).

pub fn columns<I, S>(self, columns: I) -> Self

where I: IntoIterator<Item = S>, S: Into<String>,

Set the column names. Replaces any previously set columns.

Trait Implementations

impl Clone for CatalogTable

fn clone(&self) -> CatalogTable

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CatalogTable

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

Formats the value using the given formatter.

impl Display for CatalogTable

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

Formats the value using the given formatter.

impl Eq for CatalogTable

impl FromIterator<CatalogTable> for Catalog

fn from_iter<I: IntoIterator<Item = CatalogTable>>(iter: I) -> Self

Creates a value from an iterator.

impl PartialEq for CatalogTable

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