The public API of parquet-fortran, and the only module a user needs to name:
a single use parquet brings the whole library into scope.
This module is a facade. It re-exports, unchanged, every public entity of the modules that actually implement the library:
parquet_io -- readers, writers, schemas, MAML parsing/validation,
filters, sort keys, read-time qc, file metadata.
Itself a facade over the internal parquet_core.parquet_tables -- the parquet_table container: lazy columnar reads,
slices, row handles, mutation, table write-out.parquet_columns -- the parquet_column foundation and the PK_* kind
constants.parquet_strings -- parquet_string_column/parquet_string.parquet_temporal-- parquet_date/parquet_time/parquet_timestamp
and the parquet_unit_*/parquet_ns_* constants.parquet_sorting -- pf_sort/pf_argsort/pf_permute/pf_is_sorted
and the pf_sort_keys multi-key builder.parquet_random -- counter-based random numbers: pf_random_at and
friends, reproducible under any OpenMP schedule.parquet_settings-- process-global settings: thread caps, writer
defaults, terminal verbosity and message stream,
plus the read-only parquet_max_* limits.parquet_maml_base -- parquet_maml_file, for embedded MAML schemas.parquet_version -- parquet_get_version, this library's own version
string. This facade is the ONLY module that
re-exports it: an Arrow-free tier deliberately does
not, so a program importing one of those writes its
own use parquet_version line.Those modules remain individually usable (use parquet_temporal still works
and still costs less to compile against), but nothing requires it -- every
name they export is reachable through this one. The exception is
parquet_bindings, the raw C interop layer, which is deliberately NOT
re-exported: it is an implementation detail, not user API.
This module holds no code of its own. Both version queries are re-exported
from elsewhere: parquet_get_version from the leaf parquet_version, and
parquet_get_arrow_version -- the linked Arrow/Parquet C++ versions, which
need the C++ boundary -- from parquet_settings.
