      CMRAs with partial cores. · cfb00b3e
      Robbert Krebbers authored
      Based on an idea and WIP commits of J-H. Jourdan: the core of a CMRA
      A is now a partial function A → option A.
      
      TODO: define sum CMRA
      TODO: remove one shot CMRA and define it in terms of sum

      Tweak the algebraic hierarchy. · a3d0a338
      Robbert Krebbers authored
      - Make the carrier argument of the constructors for the canonical structures
        cofeT and cmraT explicit. This way we make sure the carrier is properly
        exposed, instead of some alias of the carrier.
      - Make derived constructions (such as discreteC and discreteR) notations
        instead of definitions. This is yet again to make sure that the carrier is
        properly exposed.
      - Turn DRA into a canonical structure (it used to be a type class).
      
      This fixes some issues, notably it fixes some broken rewrites in algebra/sts
      and it makes canonical structures work properly with dec_agree.

      Also do some minor clean up.

      No longer use option for local updates. · bee413b8
      Robbert Krebbers authored
      Instead, I separate it into a total function and a predicate
      describe whether the action is allowed or not. This has some
      advantages:
      
      * It is much easier to deal with total functions and predicates
        in Coq than with functions into option.
      * Already existing functions do not need to be wrapped. Instead,
        when using a local update you end up with a sensible side
        condition as a Coq Prop.
      * The definition of local updates (and all CMRA instances) no
        longer depend on option.
