Summary#
- Adds
Configstruct to thecommoncrate (serde-deserializable from TOML) with v0.1 fields:bind_address,port,data_dir,database_url,public_url, and empty stub sections[blobs],[oauth],[iroh] EZPDS_*env var overrides (prefix:EZPDS_) applied on top of TOML via pureapply_env_overrides— no I/O in the Functional Core- Relay binary gains
--config/EZPDS_CONFIGCLI arg (clap), loads config on startup, fails fast with clear error message on invalid config; logging viaRUST_LOG-awareEnvFilter - 13 tests: TOML parsing, env var overrides, missing required field errors, I/O and parse error paths
Architecture notes#
FCIS pattern applied:
config.rs— Functional Core:Config,RawConfig,ConfigError,apply_env_overrides(takes explicit envHashMap),validate_and_buildconfig_loader.rs— Imperative Shell:load_config(reads file + real env),load_config_with_env(pub(crate)for test isolation)relay/src/main.rs— Imperative Shell: CLI parsing, config loading, structured logging
Test plan#
-
cargo test --workspace— 13 tests pass, 0 failures -
cargo clippy --workspace -- -D warnings— no warnings -
cargo fmt --all --check— clean -
cargo build --package relay— builds successfully - Manual smoke test: run
./target/debug/relay --config /nonexistent.tomland confirm error message iserror: failed to load config from /nonexistent.toml: failed to read config file: No such file or directory (os error 2) - Manual smoke test: create a minimal
relay.tomlwithdata_dirandpublic_url, run./target/debug/relayand confirm structured log line at startup
