CLRi

Slow, incompatible, buggy, unsupported CLR metadata parser (hopefully an interpreter in the future), implemented in Rust. Requires the nightly compiler.

What's implemented

• PE executable parser
• Some CLR metadata parsing
  • Image header
  • #Strings and #US string heaps
  • #~ header
  • Tagged/coded indices
  • The following metadata tables:
    • Module
    • TypeRef
    • TypeDef
    • MethodDef
    • MemberRef (MethodRef)
    • CustomAttribute
    • Assembly
    • AssemblyRef
• That's pretty much it
