Module common

Common utilities used by both directory and file traits.

Macros

• attribute_query
  Converts a lower-case attribute name into the appropriate NodeAttributesQuery flag. This is used by the attributes! macro.

Enums

• CreationMode
  Represents if and how objects should be created with an open request.

Traits

• IntoAny
  Trait to be used as a supertrait when an object should allow dynamic casting to an Any.

Functions

• decode_extended_attribute_value
• encode_extended_attribute_value
• extended_attributes_sender
• inherit_rights_for_clone
  Common logic for rights processing during cloning a node, shared by both file and directory implementations.
• io2_to_io1_attrs
  Used to translate fuchsia.io/Node.GetAttributes calls (io2) to fuchsia.io/Node.GetAttrs (io1). We don’t return a Result since the fuchsia.io/Node.GetAttrs method doesn’t use FIDL errors, and thus requires we return a status code and set of default attributes for the failure case.
• mutable_node_attributes_to_query
• rights_to_posix_mode_bits
  Returns equivalent POSIX mode/permission bits based on the specified rights. Note that these only set the user bits.
• send_on_open_with_error
  A helper method to send OnOpen event on the handle owned by the server_end in case flags contains OPEN_FLAG_STATUS.
• stricter_or_same_rights
  Returns true if the rights flags in flags do not exceed those in parent_flags.
