> [!WARNING]
> The goal of this crate is to provide decent coverage of the (large) SVG spec, up to what vello will support, for use in interactive graphics. If you are looking for a correct SVG renderer, see [resvg](https://github.com/RazrFalcon/resvg). See [vello](https://github.com/linebender/vello) for more information about limitations.
## Examples
### Cross platform (Winit)
```shell
cargo run -p with_winit
```
You can also load an entire folder or individual files.
```shell
cargo run -p with_winit -- examples/assets
```
### Web platform
Because Vello relies heavily on compute shaders, we rely on the emerging WebGPU standard to run on the web.
Until browser support becomes widespread, it will probably be necessary to use development browser versions (e.g. Chrome Canary) and explicitly enable WebGPU.
This uses [`cargo-run-wasm`](https://github.com/rukai/cargo-run-wasm) to build the example for web, and host a local server for it
```shell
# Make sure the Rust toolchain supports the wasm32 target
rustup target add wasm32-unknown-unknown
# The binary name must also be explicitly provided as it differs from the package name
cargo run_wasm -p with_winit --bin with_winit_bin
```
There is also a web demo [available here](https://linebender.github.io/vello_svg) on supporting web browsers.
> [!WARNING]
> The web is not currently a primary target for Vello, and WebGPU implementations are incomplete, so you might run into issues running this example.
## Minimum supported Rust Version (MSRV)
This version of Vello SVG has been verified to compile with **Rust 1.75** and later.
Future versions of Vello SVG might increase the Rust version requirement.
It will not be treated as a breaking change and as such can even happen with small patch releases.
Click here if compiling fails.
As time has passed, some of Velato's dependencies could have released versions with a higher Rust requirement.
If you encounter a compilation issue due to a dependency and don't want to upgrade your Rust toolchain, then you could downgrade the dependency.
```sh
# Use the problematic dependency's name and version
cargo update -p package_name --precise 0.1.1
```
