// UpdateOptions represents options that can be used to configure UpdateOne and UpdateMany operations.
type UpdateOptions struct {
	// A set of filters specifying to which array elements an update should apply. This option is only valid for MongoDB
	// versions >= 3.6. For previous server versions, the driver will return an error if this option is used. The
	// default value is nil, which means the update will apply to all array elements.
	ArrayFilters *ArrayFilters

	// If true, writes executed as part of the operation will opt out of document-level validation on the server. This
	// option is valid for MongoDB versions >= 3.2 and is ignored for previous server versions. The default value is
	// false. See https://docs.mongodb.com/manual/core/schema-validation/ for more information about document
	// validation.
	BypassDocumentValidation *bool

	// Specifies a collation to use for string comparisons during the operation. This option is only valid for MongoDB
	// versions >= 3.4. For previous server versions, the driver will return an error if this option is used. The
	// default value is nil, which means the default collation of the collection will be used.
	Collation *Collation

	// The index to use for the operation. This should either be the index name as a string or the index specification
	// as a document. This option is only valid for MongoDB versions >= 4.2. Server versions >= 3.4 will return an error
	// if this option is specified. For server versions < 3.4, the driver will return a client-side error if this option
	// is specified. The driver will return an error if this option is specified during an unacknowledged write
	// operation. The driver will return an error if the hint parameter is a multi-key map. The default value is nil,
	// which means that no hint will be sent.
	Hint interface{}

	// If true, a new document will be inserted if the filter does not match any documents in the collection. The
	// default value is false.
	Upsert *bool

	// Specifies parameters for the update expression. This option is only valid for MongoDB versions >= 5.0. Older
	// servers will report an error for using this option. This must be a document mapping parameter names to values.
	// Values must be constant or closed expressions that do not reference document fields. Parameters can then be
	// accessed as variables in an aggregate expression context (e.g. "$$var").
