## Type Marshaling
`ddbus` includes fancy templated methods for marshaling D types in and out of DBus messages.
All DBus-compatible basic types work (except dbus path objects and file descriptors).
Any forward range can be marshalled in as DBus array of that type but arrays must be taken out as dynamic arrays.
Structures are mapped to `Tuple` from `std.typecons`.
All DBus-compatible basic types work (except file descriptors).
Any forward range can be marshaled in as DBus array of that type but arrays must be taken out as dynamic arrays.
As per version 2.3.0, D `struct` types are fully supported by `ddbus`. By default all public fields of a structure are marshaled. This behavior can be [changed by UDAs](#customizing-marshaling-of-struct-types). Mapping DBus structures to a matching instance of `std.typecons.Tuple`, like earlier versions of `ddbus` did, is also still supported.
Example using the lower level interface, the simple interfaces use these behind the scenes:
```d
Message msg = Message("org.example.wow","/wut","org.test.iface","meth");
bool[] emptyB;
auto args = tuple(5,true,"wow",[6,5],tuple(6.2,4,[["lol"]],emptyB));
struct S {
double a;
int b;
string[][] c;
bool[] d;
}
auto s = S(6.2, 4, [["lol"]], []);
auto args = tuple(5, true, "wow", [6, 5], s);
msg.build(args.expand);
msg.signature().assertEqual("ibsai(diaasab)");
msg.readTuple!(typeof(args))().assertEqual(args);
```
### Basic types
These are the basic types supported by `ddbus`:
`bool`, `byte`, `short`, `ushort`, `int`, `uint`, `long`, `ulong`, `double`, `string`, `ObjectPath`
### Overview of mappings of other types:
| D type | DBus type | Comments
| -------------------------------------------- | ------------------------ | ---
| any `enum` | `enum` base type | Only the exact values present in the definition of the `enum` type will be allowed.
| `std.typecons.BitFlags` | `enum` base type | Allows usage of OR'ed values of a flags `enum`.
| dynamic array `T[]` | array |
| associative array `V[K]` | array of key-value pairs | DBus has a special type for key-value pairs, which can be used as the element type of an array only.
| `Tuple!(T...)` | structure | The DBus structure will map all of the `Tuple`'s values in sequence.
| any `struct` | structure | The DBus structure will map all public fields of the `struct` type in order of definition, unless otherwise specified using UDAs.
| `ddbus` style variant `Variant!T` | variant | `Variant!T` is in fact just a wrapper type to force representation as a variant in DBus, use `Variant!DBusAny` for actual dynamic typing.
| Phobos style variants `std.variant.VariantN` | variant | Only supported if set of allowed types is limited to types that can be marshaled by `ddbus`, so `std.variant.Variant` is not supported, but `std.variant.Algebraic` may be, depending on allowed types
### Customizing marshaling of `struct` types
Marshaling behavior can be changed for a `struct` type by adding the `@dbusMarshaling`
UDA with the appropriate flag. The following flags are supported:
- `includePrivateFields` enables marshaling of private fields
- `manualOnly` disables marshaling of all fields
Marshaling of individual fields can be enabled or disabled by setting the `DBusMarshal`
flag as an UDA. I.e. `@Yes.DBusMarshal` or `@No.DBusMarshal`.
Note: symbols `Yes` and `No` are defined in `std.typecons`.
After converting a DBus structure to a D `struct`, any fields that are not marshaled
will appear freshly initialized. This is true even when just converting a `struct` to
`DBusAny` and back.
```d
import ddbus.attributes;
import std.typecons;
@dbusMarshaling(MarshalingFlag.includePrivateFields)
struct WeirdThing {
int a; // marshaled (default behavior not overridden)
@No.DBusMarshal int b; // explicitly not marshaled
private int c; // marshaled, because of includePrivateFields
}
```
## Modules
- `thin`: thin wrapper types
- `router`: message and signal routing based on `MessagePattern` structs.
- `attributes`: defines some UDAs (and related templates) that can be used to customize
struct marshaling.
- `bus`: bus functionality like requesting names and event loops.
- `simple`: simpler wrappers around other functionality.
- `conv`: low level type marshaling methods.
- `util`: templates for working with D type marshaling like `canDBus!T`.
- `exception`: exception classes
- `c_lib`: a D translation of the DBus C headers.
- `router`: message and signal routing based on `MessagePattern` structs.
- `simple`: simpler wrappers around other functionality.
- `thin`: thin wrapper types
- `util`: templates for working with D type marshaling like `canDBus!T`.
- `c_lib`: a D translation of the DBus C headers
(you generally should not need to use these directly).
Importing `ddbus` publicly imports the `thin`,`router`,`bus` and `simple` modules.
These provide most of the functionality you probably want,
Importing `ddbus` will publicly import the `thin`, `router`, `bus`, `simple` and
`attributes` modules. These provide most of the functionality you probably want,
you can import the others if you want lower level control.
Nothing is hidden so if `ddbus` doesn't provide something you can simply import `c_lib` and use the pointers
contained in the thin wrapper structs to do it yourself.
Nothing is hidden so if `ddbus` doesn't provide something, you can always import
`c_lib` and use the pointers contained in the thin wrapper structs to do it yourself.
