Stable names

Rust	Canonical	Kind	Summary
`Cache`	`cache`	type	The cache fetcher.
`cache_key`	`cache_key`	function	Compute the cache key for a resolved URL: `sha256(utf8(url))`, lowercase hex.
`CachedBlob`	`cache_entry`	type	A resolved cache entry: the blob path plus its manifest.
`CommitReceipt`	`commit_receipt`	type	What a successful `commit` did.
`CommitToken`	`commit_token`	type	The value a writer hands the owner after `flush` (`spec/writer.md` §5.2).
`data_dir`	`data_dir`	function	Resolve the cache root `$EARTHSCIDATADIR`.
`DataSource`	`data_source`	type	The minimal parsed `DataSource` the Provider needs: where the bytes are, how to decode them, which variables to read, and the temporal cadence (absent ⇒ CONST).
`DimWindow`	`dim_window`	type	A named-dimension window, built one dimension at a time — the Rust spelling of `spec/prefetch.md` §2.2’s `DimWindow` (the run window `(start, end)` already owns the name `Window`).
`EpochSample`	`epoch_sample`	type	What `PrefetchGroup::take` returns: one `Sample` per member key.
`Error`	`error`	error	Errors raised by the cache, transports, and stores.
`Ff10Reader`	`ff10_reader`	type	The active `ff10` reader.
`file_source_is_current`	`file_source_is_current`	function	Rung 0 as a yes/no: is the source provably the file that was ingested?
`file_source_state`	`file_source_state`	function	Rung 0 without a memo: is the `file://` source behind a cached entry still the file that was ingested into it?
`GeoTiffReader`	`geotiff_reader`	type	The active `geotiff` reader: pure-Rust raster decode + tiepoint georef.
`is_offline`	`is_offline`	function	Resolve the effective offline flag: the explicit argument wins; otherwise fall back to `EARTHSCI_OFFLINE`.
`Manifest`	`manifest`	type	Validation + provenance record stored alongside every cached blob.
`NativeDataset`	`native_dataset`	type	A decoded native dataset: data variables keyed by on-disk name, plus the native coordinates of the loader’s grid.
`NativeField`	`native_field`	type	One native-grid array, keyed by its on-disk `file_variable` name and validated against `spec/schemas/native-field.schema.json`.
`NetcdfReader`	`netcdf_reader`	type	The active `netcdf` reader: pure-Rust NetCDF-3 + NetCDF-4/HDF5 decode.
`Order`	`prefetch_order`	type	The order in which epochs will be taken (`spec/prefetch.md` §3.3).
`ParquetReader`	`parquet_reader`	type	The active `parquet` reader: an Apache Parquet file as a flat table on `index`.
`PrefetchGroup`	`prefetch_group`	type	Background decode of upcoming epochs across several providers, bitwise identical to synchronous `Provider::refresh`.
`Provider`	`provider`	type	A loader-bound provider of native-grid arrays, refreshed at the loader’s cadence.
`read_blob`	`read_blob`	function	Read a committed blob.
`read_output_manifest`	`read_output_manifest`	function	Read and parse `output_manifest.json` (v1 or v2).
`read_record`	`read_record`	function	Read the `region` of committed record `index` of variable `var` (shape: the variable’s dims minus time, region-sized).
`read_static`	`read_static`	function	Read the `region` of committed static `name`.
`Region`	`region`	type	A block of the non-time dims, `dim → start..stop` (0-based, half-open).
`Role`	`writer_role`	type	A writer’s role in a store (`spec/writer.md` §5).
`Sample`	`prefetch_sample`	type	One member’s part of an epoch (`spec/prefetch.md` §3.4).
`schema_fingerprint`	`schema_fingerprint`	function	The schema fingerprint (`spec/writer.md` §3.1): `"sha256:" + hex` over the canonical JSON of the schema’s structural fields.
`sha256_file`	`sha256_file`	function	Stream a file through sha256 without loading it fully into memory.
`ShapefileReader`	`shapefile_reader`	type	The `shapefile` format reader.
`SourceTemporal`	`source_temporal`	type	The temporal nature of a loader that refreshes at a cadence (plan §4.2).
`StreamSchema`	`stream_schema`	type	The stream schema: the v1 `OutputSchema` without data, plus a time mode, statics and per-variable dtypes.
`Temporal`	`temporal`	type	A loader’s temporal nature, supplying the TTL rung of the ladder.
`TimeMode`	`indexed_time`	type	How the record axis is addressed (`spec/writer.md` §6).
`Window`	`window`	type	A run window `(start, end)` — half-open `[start, end)`.
`ZarrReader`	`zarr_reader`	type	The store-backed `zarr` reader (Zarr v3 + v2 chunked arrays, via `zarrs`).
`ZarrStreamWriter`	`stream_writer`	type	The streaming writer handle (`spec/writer.md`).
