Research direction

Start by reading rust-lang/rust#44928 and the current Rust Reference sections covering lifetimes, borrow checking, and expressions. Map the existing ad hoc material and identify what the NLL changes require; done means the checklist is addressed with coherent reference documentation and examples where appropriate.

Written by the indexing model from the issue text.

Description

RFC Stabilization Docs

See rust-lang/rust#44928. The reference currently has almost no documentation of borrowck

  • Document lifetimes (I'll try to get to this soon eventually)
  • Document borrowck in enough detail for the NLL changes to matter. The main changes are that lifetimes don't have to correspond to lexical scopes, and that 'outlives' is now will eventually be defined as happening at a point in the control flow graph, rather than globally.
  • Use in examples if there are any.
  • Move ad hoc documentation of borrowck requirements out of the expressions chapter.
