func MustHaveTag

func MustHaveTag(data interface{}, fieldName string) string

MustHaveTag gets the "bson" struct tag for a field, panicking if either the field does not exist or has no "bson" tag.

func Tag

func Tag(data interface{}, fieldName string) (string, error)

Tag returns the value of the "bson" tag for the given struct field name of the "data" struct, stripping any tag modifiers such as "omitempty". Returns the empty string if there is no tag, and an error if the field does not exist in the struct.

If data is a slice of structs, this check applies to the type of struct in the slice.
