ragrig 1.1.2

RAG framework for research and prototyping. Zero dependencies, hot-swap any agent at runtime, hybrid BM25+vector retrieval. Default build compiles with cargo build --release and nothing else.

//! Compile-time embedded test fixtures for downstream crates.
//!
//! When the `test-fixtures` feature is enabled, this module exposes the
//! contents of `tests/fixtures/formats/` as `&'static [u8]` constants and
//! as directory handles.  The build script stages a filtered copy of that
//! directory into `$OUT_DIR/fixtures` — skipping `.ragrig*` state files
//! that accumulate when the REPL runs against a fixture folder — and these
//! macros embed the staged copy, so runtime state is never compiled into
//! downstream binaries.  Downstream crates can use these to write their
//! own integration tests without needing the raw files on disk.
//!
//! # Example
//!
//! ```ignore
//! use ragrig::fixtures;
//! let pdf_bytes: &[u8] = ragrig::fixtures::pdf::NEW_STATS;
//! ```

#[cfg(feature = "test-fixtures")]
