** Architecture
*** Config datastructure

There were 3 major designs considered so far (here in chronological order).

**** Vec Based
Code sketch in https://github.com/cafkafk/seidr/commit/3d3b6d6646bda84333018cd621cd8bd6348b9cef

#+begin_src mermaid :file ./doc/img/config-struct-vec.png :width 4000px

  Co[config]
  Ca["categories (vec<category>)"]
  L[links]
  Co ==> Ca & L
  Ca ----> c1(category 1) & c2(category 2) & c3(category 3)
  subgraph Categories Vec
    c1(category 1) ==> flags1 & repos1("repos (vec<GitRepo>)")
    c2(category 2) ==> flags2 & repos2("repos (vec<GitRepo>)")
    c3(category 3) ==> flags3 & repos3("repos (vec<GitRepo>)")
    direction TB
    subgraph GitRepos
      repos1 --> gr1 & gr2 & gr3
      repos2 --> gr4 & gr5 & gr6
      repos3 --> gr7 & gr8 & gr9
    end
    direction TB
    subgraph Flags Enum
      flags1 & flags2 & flags3 -. any of .- Push & Clone
    end
  end
#+end_src

#+RESULTS:
[[file:./doc/img/config-struct-vec.png]]

**** BTreeMap Based (nested)

flowchart LR
  Co[config]
  Ca["categories (BTreeMap)"]
  L[links]
  Co ==> Ca & L
  Ca -- "unique_name/key" --> c1(category 1) & c2(category 2) & c3(category 3)
  subgraph Categories BTreeMap
    c1(category 1) ==> flags1 & repos1("repos (BTreeMap)")
    c2(category 2) ==> flags2 & repos2("repos (BTreeMap)")
    c3(category 3) ==> flags3 & repos3("repos (BTreeMap)")
    direction TB
    subgraph GitRepos
      repos1 -- "unique_name/key" --> gr1 & gr2 & gr3
      repos2 -- "unique_name/key" --> gr4 & gr5 & gr6
      repos3 -- "unique_name/key" --> gr7 & gr8 & gr9
    end
    direction TB

      flags1 & flags2 & flags3 -. any of .- Push & Clone
    end
  end
#+end_src

**** BTreeMap Based (Store)

#+begin_src mermaid :file ./doc/img/config-struct-store.png :width 4000px
flowchart LR
  S[(Store)]
  subgraph Repo Store BMapTree
    S -- "unique_name/key" ----> gr1 & gr2 & gr3
    S -- "unique_name/key" ----> gr4 & gr5 & gr6
    S -- "unique_name/key" ----> gr7 & gr8 & gr9
  end
  Co[config]
  Ca["categories (BTreeMap)"]
  L[links]
  Co ==> Ca & L
  Ca -- "unique_name/key" --> c1(category 1) & c2(category 2) & c3(category 3)
  subgraph Categories BTreeMap
    c1(category 1) ==> flags1 & repos1("repos (vec<keys>)")
    c2(category 2) ==> flags2 & repos2("repos (vec<keys>)")
    c3(category 3) ==> flags3 & repos3("repos (vec<keys>)")
    direction TB
    subgraph GitRepos
      repos1 <-. "unique_name/key" .-> gr1 & gr2 & gr3 & gr4 & gr5 & gr6 & gr7 & gr8 & gr9
      repos2 <-. "unique_name/key" .-> gr1 & gr2 & gr3 & gr4 & gr5 & gr6 & gr7 & gr8 & gr9
      repos3 <-. "unique_name/key" .-> gr1 & gr2 & gr3 & gr4 & gr5 & gr6 & gr7 & gr8 & gr9
    end
    direction TB
    subgraph Flags Enum
