v0.3.0

  • Add a :decimal column type, backed by the optional :decimal package ({:decimal, "~> 3.1"}). It rounds exactly half-up, keeps trailing zeros, and never emits scientific notation, unlike :float. Declaring a :decimal column without the package is a compile-time error; every other type is unaffected. 3.1 is required because Decimal.parse/1 in 2.x is subject to CVE-2026-32686.
  • Passing a Decimal to a :float column now raises an error pointing at the :decimal type, instead of the generic "Invalid float value".
  • Tidy the :float error messages: fix a "Cannort parse float value" typo, and stop double-quoting values that inspect/1 already quotes.
  • Fix an ArithmeticError when a nil value reached a :float column that had digits: set. nil now renders as an empty column for every type, as documented.
  • Add usage-rules.md, describing the DSL for consuming projects.
  • Fix the README examples: the column header option is header:, not label:.
