Theoretically, yes: https://doc.rust-lang.org/nomicon/ffi.html#calling-rust-code-from-c
Rust can make C-compatible static libraries and export C ABI structs and functions, which you can then pick up on the C++ side. There's even tooling like https://lib.rs/cxx that automates a lot of this.
However, I haven't prepared an interface for it, so it needs a bit of DIY. If you'd like to do it, then:
dssim-core
is the library interface with minimal dependencies (no image I/O) so it's the best one to expose. https://github.com/kornelski/dssim/tree/main/dssim-core- Create C-compatible functions that have
#[no_mangle] pub extern "C" fn
type for the functionality you need. - Write their equivalent as a C header (or use https://lib.rs/cbindgen to automate this)
- Add
[lib]\ncrate-type = ["lib", "staticlib"]
to https://github.com/kornelski/dssim/blob/main/dssim-core/Cargo.toml cargo build --release
will then maketarget/release/libdssim-core.a
that you can link with a C or C++ project
from dssim.
Thank you for the quick and detailed response!
Please consider adding such interface to the library as I think there'll be more demand to use this lib with C/C++.
