Struct KeyRelation 

pub struct KeyRelation<'a> {
    pub table: &'a str,
    pub columns: &'a [ColumnDef],
    pub partition: Option<&'a PartitionSpec>,
    pub has_primary_key: bool,
}

The relation a key’s index is built on.

Fields

table: &'a str

The relation’s catalog name.

columns: &'a [ColumnDef]

partition: Option<&'a PartitionSpec>

The relation’s own partition key, when it is partitioned.

has_primary_key: bool

The relation already has a primary key that a new one would conflict with: index_check_primary_key looks for one when ALTER TABLE adds the key or a partition declares it.
