Struct TableKeyConstraint 

pub struct TableKeyConstraint {
    pub name: Option<String>,
    pub kind: TableKeyConstraintKind,
    pub columns: Vec<String>,
    pub nulls_not_distinct: bool,
}

A table key whose columns are compared as one tuple.

Fields

name: Option<String>

kind: TableKeyConstraintKind

columns: Vec<String>

nulls_not_distinct: bool

PostgreSQL UNIQUE keys normally treat every NULL-containing tuple as distinct. UNIQUE NULLS NOT DISTINCT opts into NULL equality.
