# ccusage-adapter-hermes
The Hermes adapter: it turns the Hermes SQLite state database
into the usage entries the reports render.
## Owns
- `loader.rs` — reading the source, dedupe, and date filtering.
- `parser.rs` — raw record parsing, token mapping, and model naming.
- `paths.rs` — environment variables, default directories, and file discovery.
- `report.rs` — the JSON and table shapes where they differ from the shared ones.
Anything that is not specific to this source belongs in `ccusage-core` or
`ccusage-adapter-common` instead.
## Data source
- `${HERMES_HOME:-~/.hermes}/state.db`
Reads SQLite with the bundled `sqlite` crate, which is why this crate declares it and
most adapters do not.
## Public surface
- `loader::load_entries`
- `report::report_from_rows`
- `report::summarize_entries`
- `run`
## Depends on
- `ccusage-adapter-common`
- `ccusage-core`
- `jiff`
- `serde_json`
- `sqlite`
## Build layer
Built in the `adapters` Crane artifact layer; the layer compiles all adapters in one Cargo invocation, so they build concurrently.
