rainier-orm-macros 1.0.0

#[derive(Entity)] for rainier_orm.

From a plain struct it generates the Entity impl: table + column metadata (column SQL type is deferred to the field type's SqlType impl, so it stays open to new types), a row decoder (from_row, via each field type's FromColumn), the insert/primary-key value projections (via ToColumn), plus index and foreign-key constraint metadata. No per-entity SQL is written by hand.

#[derive(Entity)]
#[orm(table = "posts")]
#[orm(index = "author_id, created_at")]      // composite index
#[orm(unique = "author_id, slug")]           // composite unique
struct Post {
    #[orm(pk, auto_increment)]
    id: u64,
    #[orm(unique)]                            // single-column unique
    slug: String,
    #[orm(index, references = "users(id)", on_delete = "cascade")]
    author_id: u64,                            // FK *id*, not a relationship
    body: Option<String>,                      // nullable inferred from Option
    #[orm(column = "created_at")]
    created: chrono::DateTime<chrono::Utc>,
