Module common

Common utilities used by both directory and file traits.

Macros

Enums

CreationMode

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

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.
