Class Method Details

.coerce_value(value, value_type = nil, options = {}) ⇒ Object

Coerces a given value into a requested type

Parameters:

  • value (Object) —

    value to coerce

  • value_type (Symbol) (defaults to: nil) —

    requested type such as :boolean, :integer, :string, :symbol, :ssl_verify_mode, :ssl_certificate, or :ssl_key

  • options (Hash) (defaults to: {}) —

    Options Hash

Options Hash (options):

  • :coerce_nil (Boolean) —

    where to coerce nil values (defaults to true)

Returns:

  • (Object) —

    coerced value
