Generate the client

rent generate

The command reads rent/schema.rsl (or a configured multi-file RSL directory). The generated tree contains models, create/update/delete/query builders, compact field filters, composable predicates, relation loaders, and a transaction client.

Use compact methods for ordinary queries:

client
    .user()
    .email_eq("ada@example.com")
    .only()
    .await?;

Use predicate modules when an expression must be stored, combined dynamically, or reused:

let active_adult = rent::sql::ast::and([
    user_predicate::active_eq(true),
    user_predicate::age_ge(18),
]);

client.user().where_(active_adult).all().await?;

Predicates are typed SQL expression values. Most developers do not need to name them for straightforward filters.
