Expand description

A new index before it has an OID.

Fields§

§table: u32

The OID of the table.

§name: Option<String>

The name that the statement gives, or None to make one.

§columns: Vec<NewIndexColumn>

The columns: the key columns, then the INCLUDE columns.

§key_count: usize

The number of key columns.

§method: u32

The OID of the access method.

§unique: bool

True for a unique index.

§nulls_not_distinct: bool

True for NULLS NOT DISTINCT.

§constraint: Option<ConKind>

The constraint that the index is for: Primary, Unique or None.

§deferrable: bool

True for a deferrable constraint.

§deferred: bool

True for a constraint that is initially deferred.

§exprs: Option<String>

The expressions of the index columns with key 0, in the form of the analyzer.

§predicate: Option<String>

The predicate, in the form of the analyzer.

§refs: Vec<ObjRef>

The objects that the expressions and the predicate refer to.

§pages: i32

The pages of the main fork of the new index, from size::empty_index_pages.
