From Why are Option variants lang items?, we see this list of lang items.

Note that a topic of debate is whether these should be split into two categories:

  • Semantics-altering lang items (Things which cannot be expressed using pure rust, such as Box, or Fn traits)
  • Compiler-knowledge items, where the compiler "needs to know" where they are when doing desugaring, such as for loops, ? operations, etc.

Filtering for lines that have Target::Trait, we see:
