Struct CheckContract 

pub struct CheckContract {
    pub name: Option<String>,
    pub expr: String,
}

A declarative table-level CHECK. expr is an arbitrary SQL boolean fragment (bounded, not a full statement); name is auto-derived when omitted. The core reconciles it by a hash of this DECLARED spec — never by comparing to Postgres’s normalized stored definition — so there is no rewrite-churn.

Fields

name: Option<String>

expr: String
