[lib]
# Unique per-crate artifact name (the shared workspace target/ dir cannot hold
# multiple `lib_core` cdylibs). The importable Python module is `_multimodal`: the
# name comes from the `#[pymodule]` entry point and the setuptools-rust target,
# which renames the built artifact.
name = "sglang_mm_core"
# cdylib: the PyO3 module (`sglang.srt.rust_extensions._multimodal`).
# rlib:   pure-Rust core linked by sglang-server's Rust MM path.

[features]
# Both features are deliberately NOT default: cargo unifies a package's
# features across everything selected in one invocation, so anything default-on
# here would leak back into sglang-server's copy of this crate under
# `cargo build --workspace` even though the server depends on it with
# `default-features = false`. Opting in explicitly keeps the pure-Rust core
# pure no matter how the workspace is built; the wheel asks for both via
# `[package.metadata.sglang] features` above.

python = ["dep:pyo3", "dep:numpy"]
# Fan work out onto crate-owned rayon pools (see `common::par`). Off for the
# rlib: sglang-server provides concurrency across requests and owns its core
# budget, so preprocessing runs inline on the calling thread and rayon is not
# linked at all. Orthogonal to `python` so both shapes stay testable.
