Overview

One column of a table, in the vocabulary DefaultMask.for speaks:

  • type is an ActiveRecord-ish symbol (:string, :integer, ...) or nil when the database type has no equivalent there. nil is deliberate and safe: DefaultMask emits no mask for a type it does not recognize, so an exotic column is exported unmasked-but-flagged rather than masked with a value it cannot hold.
  • limit is the character length for text-ish columns, else nil.
  • array marks a PostgreSQL ARRAY column, where no scalar mask fits.
  • default is the column's default as a Ruby scalar, or nil when it is absent or is an expression the database evaluates per row.
