Crate a2lfile[−][src]
Expand description
a2lfile is a library that allows you to read, modify and write a2l files.
It is fast, preserves the formatting of the input, and has support for files using standard version 1.71.
Macros
The a2ml_specification! macro enables application to conveniently decode and use IF_DATA defined though A2ML. The macro uses an “enhanced A2ML” language to define the items. Rust data structures and associated code will be generated for items defined inside of the macro.
