fn search_fields() -> &'static [&'static str]

Text columns to include in full-text / ILIKE search.

fn private_fields() -> &'static [&'static str]

Response fields visible only to the row owner and platform/root callers (@private). Stripped for everyone else.

fn secret_fields() -> &'static [&'static str]

Response fields (camelCase) that never leave the server (@sensitive): no caller is served them, a platform caller or the row’s owner included.

fn relation_secret_fields(_relation: &str) -> &'static [&'static str]

The @sensitive fields (camelCase response keys) of the model a to-one relation points at, stripped from the related row an ?include= expands. Keyed by the relation name of relations. Default: none.

fn owner_field() -> Option<&'static str>

The response field (camelCase) holding the owner/company id (@owner), compared against the caller’s access scope to decide private-field visibility. None = the entity has no owner concept.

fn company_field() -> Option<&'static str>

The DB column that scopes rows to a company (snake_case, e.g. company_id). None = the entity is global (reference data) and is not fenced.

fn relations() -> &'static [(&'static str, &'static str, &'static str)]

To-one relations expandable via ?include=<name>, as (relation_name, target_table, local_fk_field) — all response keys (relation_name/local_fk in camelCase; target_table is the DB table). Default: none.
