Compilation error with Opencv version 5

[JRazek]

Hi, I'm having trouble compiling the project after the update of opencv. I import opencv with:

opencv = { version = "0.99.0", features = ["clang-runtime", "calib3d", "imgproc", "video", "videoio", "highgui", "dnn", "tracking", "rgb", "imgcodecs"], default-features = false }

rustc version:

rustc 1.98.0-nightly (654079540 2026-06-12)

opencv version:

local/opencv-cuda 5.0.0-6

I use arch.

error message:

error[E0425]: cannot find type `Feature2D` in module `crate::features2d`
12881 |     ptr_extern! { crate::features2d::Feature2D,
      |                                      ^^^^^^^^^ not found in `crate::features2d`
error[E0405]: cannot find trait `Feature2DTraitConst` in module `crate::features2d`

and so on, only Feature2D seems to be affected.

Thank you for the report, I can confirm the issue. While I'm working on a fix, as a workaround you can try enabling the features module too.

This is now fixed in v0.99.1
