Expand description

Attribute markers for PostgresTable derive macro.

These const markers are used within #[column(...)] and #[PostgresTable(...)] attributes. Import them from the prelude to get IDE hover documentation.

§Example

fn main() {
use drizzle::postgres::prelude::*;

#[PostgresTable(
    NAME = "users",
    UNLOGGED,
    RLS,
    UNIQUE(columns(email, tenant_id)),
    CHECK(name = "users_score_check", expr = "score >= 0")
)]
struct User {
    #[column(PRIMARY, SERIAL)]
    id: i32,
    #[column(UNIQUE)]
    email: String,
    tenant_id: i32,
    score: i32,
    metadata: String,
}
}
