Struct EntityRef 

Source
pub struct EntityRef<'a> {
    pub schema: Option<&'a str>,
    pub name: &'a str,
    pub is_identity_table: bool,
    pub columns: &'a [&'a str],
    pub partition_column_type: Option<&'a DataType>,
}
Expand description

Lightweight reference to a target entity for storage rendering.

Carries only what storage rendering needs, so the contract does not depend on Razeri’s full design model.

Fields§

§schema: Option<&'a str>

Optional schema/database namespace.

§name: &'a str

Entity name (without schema qualifier).

§is_identity_table: bool

Whether this rendering targets the entity’s identity table (*_identity) rather than the primary table. Identity tables generally do not partition.

§columns: &'a [&'a str]

Column names of the target table, in declaration order. Required by dialects whose index DDL must enumerate columns explicitly — for example T-SQL CREATE NONCLUSTERED COLUMNSTORE INDEX ... (col, ...), which fails with Msg 35336 if the column list is missing. Empty when the caller does not have column information; renderers that need columns must skip emission and warn rather than emit invalid DDL.

§partition_column_type: Option<&'a DataType>

The declared type of the plan’s partition column, when the caller knows it.

Some platforms spell a partition differently per column type, and spell it wrong without this. GoogleSQL accepts DATE(<timestamp_column>) and DATE(<datetime_column>), and it accepts a DATE column only bare — PARTITION BY DATE(<date_column>) is refused with the grammar quoted back (measured on the service, 2026-09-07). A renderer that cannot tell the three apart has to guess, and one of its guesses is invalid DDL.

None when the caller has no type information; a renderer must then emit only what is valid for every type it could be, or emit nothing.
