dr_contract_policy()

Keep identity, columns and keys in dr_contract() and compose policy only when required. This builds a new definition without I/O. Changing a registered contract still requires a new version before registration or publication.

Usage

dr_contract_policy(
  x,
  required = x$required,
  allow_empty = x$allow_empty,
  allow_extra = x$allow_extra,
  max_age_hours = x$max_age_hours,
  constraints = x$constraints
)

Arguments

x: Contract specification.
required: Non-null columns; keys always remain non-null.
allow_empty, allow_extra: Whether empty deliveries or extra columns are allowed.
max_age_hours: Freshness limit, or NULL for no freshness monitoring.
constraints: Named per-column min, max, enum, nullable, timezone or precision checks.

Value

An updated contract specification.

Examples

dr_contract("orders", columns = c(id = "integer"), key = "id") |>
  dr_contract_policy(allow_extra = TRUE)
