PropertyDamage.AssertionFailed exception (PropertyDamage v0.2.0)

Simple exception for assertion failures.

This exception is raised by PropertyDamage.fail!/2 and provides a convenient way to fail assertions with a message and optional data.

Usage

PropertyDamage.fail!("balance is negative")
PropertyDamage.fail!("balance is negative", balance: -50, account_id: "acc_123")

Custom Exceptions

For richer error context, define your own exception types:

defmodule MyApp.BalanceViolation do
  defexception [:balance, :account_id, :requirement]

  def message(%{balance: b, account_id: id}) do
    "Account #{id} has negative balance: #{b}"
  end
end

# In your projection:
raise %MyApp.BalanceViolation{balance: -50, account_id: "acc_123", requirement: "REQ-001"}

The framework is exception-agnostic - it will catch and report any exception type.
