A signature is a list of D-Bus types, obeying some basic rules of validity.
The rules of signature validity are complex: see http://dbus.freedesktop.org/doc/dbus-specification.html#message-protocol-signatures for details.

.

parseSignature
.

Convert a list of types into a valid signature.
Throws if the given types are not a valid signature.

Throws an exception if the given types are not a valid signature.

Minimal complete definition
Instances
class IsVariant a => IsValue a where #
Value types can be used as items in containers, such as lists or dictionaries.
Users may not provide new instances of IsValue
because this could allow
containers to be created with items of heterogenous types.
Instances
class IsValue a => IsAtom a where #
Atomic types can be used as keys to dictionaries.
Users may not provide new instances of IsAtom
because this could allow
dictionaries to be created with invalid keys.
Variants may contain any other built-in D-Bus value. Besides
representing native VARIANT
values, they allow type-safe storage and
inspection of D-Bus collections.

Constructors
vectorToBytes :: Vector Value -> ByteString #
variantType :: Variant -> Type #
Every variant is strongly-typed; that is, the type of its contained value is known at all times. This function retrieves that type, so that the correct cast can be used to retrieve the value.
newtype ObjectPath #
Object paths are special strings, used to identify a particular object exported from a D-Bus application.
Object paths must begin with a slash, and consist of alphanumeric characters separated by slashes.
See http://dbus.freedesktop.org/doc/dbus-specification.html#message-protocol-marshaling-object-path for details.

newtype InterfaceName #
Interfaces are used to group a set of methods and signals within an exported object. Interface names consist of alphanumeric characters separated by periods.
See http://dbus.freedesktop.org/doc/dbus-specification.html#message-protocol-names-interface for details.
Constructors

Instances
parseInterfaceName :: MonadThrow m => String -> m InterfaceName #
interfaceName_ :: String -> InterfaceName #

newtype MemberName #
Member names are used to identify a single method or signal within an interface. Method names consist of alphanumeric characters.

Bus names are used to identify particular clients on the message bus. A bus name may be either unique or well-known, where unique names start with a colon. Bus names consist of alphanumeric characters separated by periods.
See http://dbus.freedesktop.org/doc/dbus-specification.html#message-protocol-names-bus for details.

parserBusName :: Parser () #
A D-Bus Structure is a container type similar to Haskell tuples, storing
values of any type that is convertable to IsVariant
. A Structure may
contain up to 255 values.
Most users can use the IsVariant
instance for tuples to extract the
values of a structure. This type is for very large structures, which may
be awkward to work with as tuples.
structureItems :: Structure -> [Variant] #
A D-Bus Array is a container type similar to Haskell lists, storing zero or more values of a single D-Bus type.
Most users can use the IsVariant
instance for lists or vectors to extract
the values of an array. This type is for advanced use cases, where the user
wants to convert array values to Haskell types that are not instances of
IsValue
.
Constructors

ArrayBytes ByteString |
arrayItems :: Array -> [Variant] #
data Dictionary #
A D-Bus Dictionary is a container type similar to Haskell maps, storing zero or more associations between keys and values.
Most users can use the IsVariant
instance for maps to extract the values
of a dictionary. This type is for advanced use cases, where the user
wants to convert dictionary items to Haskell types that are not instances
of IsValue
.

Defined in DBus.Internal.Types |
dictionaryItems :: Dictionary -> [(Variant, Variant)] #
A value used to uniquely identify a particular message within a session. Serials are 32-bit unsigned integers, and eventually wrap.
serialValue :: Serial -> Word32 #
firstSerial :: Serial #
Get the first serial in the sequence.
nextSerial :: Serial -> Serial #
Get the next serial in the sequence. This may wrap around to
firstSerial
.
