Struct Config 

#[non_exhaustive]
pub struct Config {
    pub schema: Vec<PathBuf>,
    pub queries: Vec<PathBuf>,
    pub output: PathBuf,
    pub resource: Option<String>,
    pub dry_run: bool,
    pub check: bool,
    pub force: bool,
    pub lenient: bool,

    pub derive: Vec<Derive>,
    pub relationships: BTreeMap<String, BTreeMap<String, RelationshipChange>>,
}

What to generate and how: the one configuration model behind the CLI and generate.

New fields may be added in minor releases, so build a Config from Config::default and assign the fields you need:

let mut config = rok_sqlc::Config::default();
config.schema = vec!["migrations/0001_init.sql".into()];
config.output = "src/db".into();
rok_sqlc::generate(&config)?;

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

schema: Vec<PathBuf>

Schema inputs, combined in the order given: a file, or a directory whose *.sql migrations are read in filename order, skipping *.down.sql.

queries: Vec<PathBuf>

Annotated query files or directories. A single file becomes the generated queries.rs. A directory (its *.sql files) or several inputs become one queries/<stem>.rs module per file, declared by a generated queries/mod.rs; each stem must be a snake_case Rust module name, and stems must be unique.

Switching between the two layouts removes the old layout’s generated files as stale. Left empty, a previously generated queries.rs or queries/ is kept and still declared.

output: PathBuf

The directory generated modules are written to. Defaults to src/db.

resource: Option<String>

Generate only the table with this SQL or module name.

dry_run: bool

Plan the run and report it without touching the filesystem.

check: bool

Write and remove nothing; report missing, changed, and stale files. Any such drift fails the run. Takes precedence over dry_run.

force: bool

Overwrite existing files that were not generated by rok-sqlc.

lenient: bool

Skip unsupported tables and queries (listed in the report) instead of failing.

conventions: Conventions

Opt-in conventions about what certain columns mean across tables. All off by default; Conventions::rok gives the Rok preset.

derive: Vec<Derive>

Extra derives for the generated rows, typed ids, key structs, enums, inputs, and patches (ADR 0013). Empty by default.

relationships: BTreeMap<String, BTreeMap<String, RelationshipChange>>

Renames and opt-outs of inferred relationships (ADR 0014), by table (its SQL name, schema-qualified name, or module name) and then by the relationship’s inferred name. Empty by default.

use rok_sqlc::RelationshipChange;
let mut config = rok_sqlc::Config::default();
let invoices = config.relationships.entry("invoices".into()).or_default();
invoices.insert("created_by_user".into(), RelationshipChange::Rename("author".into()));
invoices.insert("approved_by_user".into(), RelationshipChange::OptOut);
