3 This doc is about the [[https://en.wikipedia.org/wiki/Foreign_function_interface][Foreign Function Interface]] (FFI) features of the
4 =core=.
5 
6 Besides accessing system, OS, and external libraries via binding code
7 (dynamically in Lisp, statically in Rust), we also expose parts of the
8 core in a C-compatible fashion. In Lisp, we use the SB-ALIEN interface
9 to load (with dlopen) and call foreign symbols. In Rust we mostly use
10 rust-bindgen and the built-in rustc features.
11 
12 * Libraries
13 The following binding libraries are provided with supporting
14 code. There is some cross-over between the Lisp and Rust bindings
15 depending on what library features we need and where. Some of the
16 bindings are very minimal or for experimental-use only only.
17 ** xkb
18 These bindings are actually directed at libxkbcommon instead of
19 x11/xkb directly.

22 ** rocksdb
23 [[https://github.com/facebook/rocksdb/wiki][RocksDB Wiki]]
24 ** btrfs
25 The kernel headers btrfs and btrfs_tree will be wrapped at some point
26 in addition to the userspace library (btrfsutil) documented below.

38 ** blake3
39 temporary package for CL implementation of Blake3 SHA. Wraps C
40 implementation (libblake3).
41 ** bqn
42 These bindings are for libcbqn which can be build from CBQN:

46 bindings for ngn/k (libk).
