kglite-c 0.10.3

C ABI for kglite — stable extern "C" surface over the kglite engine so non-Rust bindings (Go via cgo, JavaScript via napi, JVM via JNI, .NET via P/Invoke, …) consume a single C header rather than re-implementing wrappers in their host language. The Rust types (DirGraph, Session, CypherResult, KgErrorCode) live in the sibling `kglite` crate; this crate is glue.

[parse]

[defines]
# Map Cargo features to C preprocessor defines so the generated
# header wraps feature-gated items in matching `#ifdef` blocks.
# Consumers building against a `libkglite_c` with feature X must
# `#define KGLITE_FEATURE_X` before including `kglite.h`, or the
# corresponding declarations are skipped. This keeps the header
# linkable: a kglite-c built without `sodir` won't export
# `kglite_datasets_sodir_fetch_all`, and the matching `#ifdef`
# hides the declaration so callers can't accidentally reference
# an undefined symbol.
