D-Bus errors can be defined by creating a YAML file to describe the errors.
From this YAML file, both documentation and binding code may be generated.
The generated bindings are C++ exception types corresponding to the D-Bus
error name. Ex. org.freedesktop.Example.Error.SomeError will create a
generated exception type of
sdbusplus::org::freedesktop::Example::Error::SomeError which may be thrown
or caught as appropriate. If the error is thrown from an interface method
which has specified it may return that error, then the bindings will generate
a catch clause that returns a D-Bus error like
"org.freedesktop.Example.Error.SomeError" to the method caller.
The error YAML is simply a list of name and optional description properties.
Example:
- name: SomeError
- name: AnotherError
description: >
This is another error.
