# Diamond Rust Binary Architecture — profile templates # # P27 ships two profiles, because the binary that serves requests on a # laptop has a different pressure target than the binary that flies on a # CubeSat or runs on a phone. # # Paste ONE of these into your Cargo.toml. Pick by deployment target: # # [profile.diamond] = SPEED-Diamond. For laptops, servers, # request-serving binaries. CPU wins. Binary # grows 10-30% in exchange for ~15-30% # faster hot paths, better cache locality, # cross-crate inlining. # # [profile.diamond-edge] = SIZE-Diamond. For phones, edge compute, # LoRa mesh nodes, embedded systems, CubeSats, # on-device AI. Bytes win. Binary shrinks # 10-25% in exchange for slightly slower hot # paths (but still fast because LTO is still on). # # Both profiles are Diamond. The difference is which pressure dominates. # Build with: cargo build --profile=diamond (speed) # cargo build --profile=diamond-edge (size) # # Canonical source: https://cochranblock.org/diamond-profile.toml # Protocol: https://cochranblock.org/arch#p27 # License: Unlicense. Fork, strip, ship as your own. Red crayons forever. # ─── SPEED-DIAMOND ────────────────────────────────────────────────── # For laptops, servers, desktops, and anything request-serving. Runtime # hot paths dominate total cost over binary-distribution size. Pick this # when the binary lives on fewer machines and handles more requests. [profile.diamond] inherits = "release" opt-level = 3 # maximum LLVM speed optimizations lto = "fat" # cross-crate inlining, full monomorphized dedup codegen-units = 1 # one crystal, no fracture planes strip = true # symbols don't run, they just ride along panic = "abort" # cull unwinding machinery (-50-300 KB) overflow-checks = false # trust the arithmetic, check explicitly when needed debug = false # DWARF is heavy incremental = false # incremental caches are fracture planes split-debuginfo = "off" # no separate .dSYM or .pdb # ─── SIZE-DIAMOND (edge) ──────────────────────────────────────────── # For phones, edge compute, spacecraft, embedded, and anything where # the binary ships to many places and every byte crosses a bandwidth- # constrained link. Pick this when binary size dominates runtime hot- # path speed. [profile.diamond-edge] inherits = "release" opt-level = "s" # size-prioritized LLVM optimizations lto = "fat" # still fat — we want the dedup even for size codegen-units = 1 # still one crystal strip = true # still stripped panic = "abort" # still no unwinding overflow-checks = false # still no runtime overflow checks debug = false # still no debug info incremental = false # still no incremental caches split-debuginfo = "off" # still no separate debug files # ─── PICKING BY PROJECT ───────────────────────────────────────────── # # Laptop/server-class (speed-Diamond): # - cochranblock (this site, serves requests) # - approuter (reverse proxy, serves requests) # - kova (local AI engine, CPU-bound inference) # - rogue-repo (payment engine, hot paths) # - tmuxisfree (fleet orchestrator, CPU-bound dispatch) # - exopack (test-augmentation, CI-speed matters) # - whobelooking (OSINT aggregator, CPU-bound JSON work) # # Edge / mobile / spacecraft-class (size-Diamond): # - pixel-forge (Android APK, Google Play distribution) # - ghost-fabric (LoRa mesh node, 915 MHz constrained) # - pocket-server (phone-hosted web server) # - call-shield (on-device call screening, sub-ms constraint) # - aptnomo (already 312 KB — Size-Diamond territory) # - any future LEO smallsat baremetal Rust payload # - any future NanoSign-signed safetensors inference binary # # When in doubt: if the binary ships to more than ~10 machines, lean # size-Diamond. If the binary serves more than ~10 requests/sec on a # single machine, lean speed-Diamond. # ─── POST-BUILD COMPRESSION (both profiles) ───────────────────────── # # After cargo build --profile=, further compress with: # # upx --best --lzma target/diamond/my-binary # upx --best --lzma target/diamond-edge/my-binary # # Cuts 50-70% more off typical binaries. Warning: corporate AV flags # UPX'd binaries. Only UPX for distribution where users know what they # run. Don't UPX anything scanned by enterprise AV. # ─── GEOLOGY REPORT (both profiles) ───────────────────────────────── # # Record binary size after each build: # # ls -la target/diamond/my-binary | awk '{print $5}' >> binary-sizes.log # ls -la target/diamond-edge/my-binary | awk '{print $5}' >> binary-sizes-edge.log # # Commit both logs. Every line is a pressure pass. Watch the numbers # fall until they can't fall further. That's when you have diamond.
