Fields

id: IndexId

name: String

index_item: Vec<ExprImpl>

Only InputRef and FuncCall type index is supported Now. The index of InputRef is the column index of the primary table. The index_item size is equal to the index table columns size The input args of FuncCall is also the column index of the primary table.

index_type: IndexType

primary_table: Arc<TableCatalog>

created_at_epoch: Option<Epoch>

initialized_at_epoch: Option<Epoch>

created_at_cluster_version: Option<String>

initialized_at_cluster_version: Option<String>

Trait Implementations

impl Clone for IndexCatalog

fn clone(&self) -> IndexCatalog

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for IndexCatalog

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

Formats the value using the given formatter.

impl Hash for IndexCatalog

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

impl OwnedByUserCatalog for IndexCatalog

fn owner(&self) -> u32

Returns the owner of the catalog.

impl PartialEq for IndexCatalog

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