keel-abi-0.1.0.0: keel-abi.cabal

cabal-version:      3.0
name:               keel-abi
version:            0.1.0.0
synopsis:           Arrow C Data/Stream Interface and DLPack, no cbits
description:
    Hand-written @Storable@ bindings for the two frozen C ABIs of the
    data-science world: the Apache Arrow C Data \/ C Stream Interface and
    DLPack's @DLManagedTensorVersioned@ — import and export directions.
    .
    The shipped library contains no C sources and needs no C toolchain
    beyond what GHC itself bundles: the structs are frozen ABIs, so their
    layouts are written out by hand for 64-bit pointers — the library
    refuses to build on any other architecture — and a /test-suite-only/
    C file of @_Static_assert(offsetof(...))@ checks fails CI if the
    hand layouts ever disagree with a real C compiler.
