nad_manifest() reads the local manifest written as county Parquet files are
installed. The Parquet path remains the primary existence check used by
nad(); the manifest provides a compact inventory and integrity metadata for
validation and portable NAD fuel bundles.
Usage
nad_manifest(version = 23L, validate = FALSE)
Arguments
- version
integer, length one; NAD revision to inventory. Only revision
23 is supported.
- validate
logical, length one; validate every manifest row against its
county Parquet file, including its schema, row count, byte size, and SHA-256
digest? This can be slow for a large inventory.
Value
A tibble with one row per installed county and columns
county_fips, state, county, row_count, size_bytes, sha256,
nad_revision, and installed_at.
Examples
nad_manifest()
#> # A tibble: 0 × 8
#> # ℹ 8 variables: county_fips <chr>, state <chr>, county <chr>, row_count <int>,
#> # size_bytes <dbl>, sha256 <chr>, nad_revision <int>, installed_at <chr>
