Rust low-level FFI bindings to SFCGAL C API.
Don't use this crate directly, prefer it's higher-level wrapper : sfcgal-rs.
This crate contains a few lines of C code (compiled as a static library with cc crate) wrapping SFCGAL C API in order to replace the error and warning handlers (which use printf by default).
It expects SFCGAL to be installed as a system library and that you have the header file for it's C API.
Then bindgen is run to generate these low-levels bindings.
In addition to all the sfcgal_ types and functions, this crate expose :
- a Rust initialize function: it calls sfcgal_init() function then it calls a custom w_sfcgal_init_handlers() function which replace the error and warning handlers from printf to a char buffer. That initialize function internally uses std::sync::ONCE_INIT to ensure it's only called once.
- two C functions w_sfcgal_get_last_error and w_sfcgal_get_last_warning which repectively reads the buffer containing the error message and the buffer containing the warning message.
In the future it could probably be improved by not requiring SFCGAL to be installed as a system library.
