Module src_ref 

Source code references.

All errors which occur while parsing or evaluating µcad code need to be reported and therefore need to address a place in the code where they did appear. A bunch of structs from this module provide this functionality:

• SrcRef boxes a SrcRefInner which itself includes all necessary reference information like line/column and a hash to identify the source file.
• Refer encapsulates any syntax element and puts a SrcRef beside it.
• SrcReferrer is a trait which provides unified access to the SrcRef (e.g. implemented by Refer).

Structs

LineCol

Refer

SrcRefInner

Traits
