Implementations

source

impl DBusMessage

source

pub fn new() -> DBusMessage

Creates a new empty DBusMessage.

Returns

A DBusMessage. Free with g_object_unref().

source

pub fn from_blob(
blob: &[u8],
capabilities: DBusCapabilityFlags
) -> Result<DBusMessage, Error>

Creates a new DBusMessage from the data stored at blob. The byte order that the message was in can be retrieved using byte_order().

If the blob cannot be parsed, contains invalid fields, or contains invalid headers, IOErrorEnum::InvalidArgument will be returned.

`blob`

A blob representing a binary D-Bus message.

`capabilities`

A DBusCapabilityFlags describing what protocol features are supported.

Returns

A new DBusMessage or None if error is set. Free with g_object_unref().

source

pub fn new_method_call(
 name: Option<&str>,
 path: &str,
 interface_: Option<&str>,
 method: &str
) -> DBusMessage

Creates a new DBusMessage for a method call.

Returns

A DBusMessage. Free with g_object_unref().

source

pub fn new_signal(path: &str, interface_: &str, signal: &str) -> DBusMessage

Creates a new DBusMessage for a signal emission.

Returns

A DBusMessage. Free with g_object_unref().

pub fn copy(&self) -> Result<DBusMessage, Error>

source

pub fn arg0(&self) -> Option<GString>

Convenience to get the first item in the body of self.

Returns

The string item or None if the first item in the body of self is not a string.

source

pub fn body(&self) -> Option<Variant>

Gets the body of a message.

Returns

A glib::Variant or None if the body is empty. Do not free, it is owned by self.

source

pub fn byte_order(&self) -> DBusMessageByteOrder

Gets the byte order of self.

pub fn destination(&self) -> Option<GString>

Convenience getter for the DBusMessageHeaderField::Destination header field.

pub fn error_name(&self) -> Option<GString>

Convenience getter for the DBusMessageHeaderField::ErrorName header field.

pub fn flags(&self) -> DBusMessageFlags

Flags that are set (typically values from the DBusMessageFlags enumeration bitwise ORed together).

Gets a header field on self.

The caller is responsible for checking the type of the returned glib::Variant matches what is expected.

`header_field`

A 8-bit unsigned integer (typically a value from the DBusMessageHeaderField enumeration)

Returns

A glib::Variant with the value if the header was found, None otherwise. Do not free, it is owned by self.

source

pub fn interface(&self) -> Option<GString>

Convenience getter for the DBusMessageHeaderField::Interface header field.

pub fn is_locked(&self) -> bool

Checks whether self is locked. To monitor changes to this value, conncet to the signal::glib::Object::notify signal to listen for changes on the property::DBusMessage::locked property.

Returns

true if self is locked, false otherwise.

source

pub fn member(&self) -> Option<GString>

Convenience getter for the DBusMessageHeaderField::Member header field.

pub fn message_type(&self) -> DBusMessageType

Gets the type of self.

This method is only available on UNIX.

The file descriptors normally correspond to G_VARIANT_TYPE_HANDLE values in the body of the message. For example, if [glib::Variant::handle()][crate::glib::Variant::handle()] returns 5, that is intended to be a reference to the file descriptor that can be accessed by g_unix_fd_list_get (list, 5, ...).

Returns

A UnixFDList or None if no file descriptors are associated. Do not free, this object is owned by self.

source

source

pub fn set_unix_fd_list(&self, fd_list: Option<&impl IsA<UnixFDList>>)

Available on Unix only.

Sets the UNIX file descriptors associated with self. As a side-effect the DBusMessageHeaderField::NumUnixFds header field is set to the number of fds in fd_list (or cleared if fd_list is None).

This method is only available on UNIX.

When designing D-Bus APIs that are intended to be interoperable, please note that non-GDBus implementations of D-Bus can usually only access file descriptors if they are referenced by a value of type G_VARIANT_TYPE_HANDLE in the body of the message.

`fd_list`

A UnixFDList or None.

Otherwise this method encodes the error in self as a glib::Error using g_dbus_error_set_dbus_error() using the information in the DBusMessageHeaderField::ErrorName header field of self as well as the first string item in self’s body.

Returns

true if error was set, false otherwise.

source
