autosar-data-specification 0.2.0

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:

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 [ElementName]s and [ElementType]s, 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

# use autosar_data_specification::*;
# use std::str::FromStr;
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) {
// ...
}

// ...
}
