Shared Memory Across Rust Projects

Configure llmenv's memory backend (ICM) so every project tagged rust shares the same long-term memory context, instead of each repo getting its own.

Config​

# ~/.config/llmenv/config.yaml

host:
  memory-server:
    addr: "192.168.1.50"

features:
  memory:
    - server_host: memory-server
      port: 9092
      when: [rust]
# Any Rust project: /path/to/any-rust-repo/.llmenv.yaml

tags: [rust]

How it works​

  • rust is a plain activation tag, contributed by any project marker with tags: [rust] — same selection model as bundles and MCP servers.
  • When rust is in the active tag set, this features.memory entry fires and llmenv points the adapter at memory-server:9092.
  • Every Claude Code session in every repo tagged rust resolves to the same memory backend, so decisions/patterns recorded in one Rust project are recallable from any other.

Scoping instead of sharing​

At most one features.memory entry can be active per scope — the resolver errors if two entries' tags match simultaneously. So isolation is a tagging decision, not a backend flag: give a project a tag that doesn't intersect the shared entry's when, or add a second entry with its own host/tag pair for a project (or group of projects) that should have private memory instead:

features:
  memory:
    - server_host: memory-server
      port: 9092
      when: [rust]              # shared pool
    - server_host: memory-server
      port: 9093
      when: [proprietary-repo]  # private — different port, different tag

Verify​

cd /path/to/any-rust-repo
llmenv doctor
llmenv context   # shows the resolved memory host/port for the active tags
