# pylon-cxx-rs
[](https://crates.io/crates/pylon-cxx)
Rust wrapper of the Pylon libraries for Basler cameras using [CXX](https://crates.io/crates/cxx).
## Platform support
Windows, linux, and macOS are all tested.
## async stream with tokio
Enable async stream support using tokio with the cargo feature `stream`. This
feature is currently not compatible with Windows (help wanted).
## Building
This crate expects to find the Pylon developer kit at the usual install
location. Build with normal rust commands. For example, to run the `grab` example:
cargo run --example grab
### On macOS
On macOS, check this:
https://github.com/basler/pypylon/issues/6#issuecomment-403090732 In other
words, do this:
```
export LD_LIBRARY_PATH=/Library/Frameworks/pylon.framework/Libraries
```
## Camera emulation
See [Basler's documentation](https://docs.baslerweb.com/camera-emulation.html). This can
simulate different frame rates, failures, etc.
```text
# on bash (e.g. linux)
export PYLON_CAMEMU=2
```
```text
# in Windows Powershell
$Env:PYLON_CAMEMU=2
```
