## nss_sys

Low-level NSS bindings for Rust.

This crate defines low-level FFI bindings for NSS. They are maintained by hand.

The directory structure of this crate is meant to mirror that of NSS itself.
For each header file provided by NSS, there should be a corresponding `.rs` file
in the `nss_sys::bindings` module that declares the corresponding functions and
data types.

To add new bindings in this crate, you'll need to:

* Identify the NSS header file that contains the functionality of interest.
* Edit the Rust file of the corresponding name under `./src/bindings`.
    * If one doesn't currently exist then create it.
* Add `#[recpr(C)]` structs and `pub extern "C"` functions as necessary to make the
  new functionality visible to Rust.
