Crate autosar_data_specification

Expand description

Specification of the Autosar arxml file format in the form of rust data structures

This crate exists to support the autosar-data crate.

The Autosar data model is originally specified as .xsd files - one for each version of the standard. All these separate xsd files were parsed into data structures and combined; this crate contains the combined specification data of all 18 Autosar 4 standard revisions.

Supported standards:

xsd filename	description
AUTOSAR_4-0-1.xsd	AUTOSAR 4.0.1
AUTOSAR_4-0-2.xsd	AUTOSAR 4.0.2
AUTOSAR_4-0-3.xsd	AUTOSAR 4.0.3
AUTOSAR_4-1-1.xsd	AUTOSAR 4.1.1
AUTOSAR_4-1-2.xsd	AUTOSAR 4.1.2
AUTOSAR_4-1-3.xsd	AUTOSAR 4.1.3
AUTOSAR_4-2-1.xsd	AUTOSAR 4.2.1
AUTOSAR_4-2-2.xsd	AUTOSAR 4.2.2

Since the raw data is rather opaque, it is not exposed directly, but rather there are functions to interact with it.

Using the crate

The main datatype is the ElementType. The type of the element at the root of every arxml file is available as ElementType::ROOT.

Note

It is not possible to directly convert between ElementNames and ElementTypes, since this is an n:m mapping. If the content of two differently named elements is structurally identical, then they have the same ElementType; on the other side there are several elements that have different content depending in the context in which they appear.

Example

let root_type = ElementType::ROOT;

// parsing an element
let element_name_text = "AR-PACKAGES";
let element_name = ElementName::from_str(element_name_text).unwrap();
assert_eq!(element_name, ElementName::ArPackages);

let version_mask = AutosarVersion::Autosar_4_3_0 as u32;
if let Some((element_type, index_list)) = root_type.find_sub_element(
    element_name,
    version_mask
) {
    // parsing an attribute
    let attribute_name = AttributeName::from_str("UUID").unwrap();
    if let Some(attribute_spec) = element_type.find_attribute_spec(attribute_name) {
        // ...
    }

    // ...
}
