Warning
As Tauri v2 is now stable, all upstream projects have upgraded and this repository is no longer revelant.
This repository contains adapters and documentation around using Tauri v2 with specta-rs projects (rspc, specta & tauri-specta).
This repository will be archived and it's changes upstreamed once Tauri v2 is released as stable in the coming months.
This is primarily targetted at early adopters.
| Tauri v1 | Tauri v2 | |
|---|---|---|
| rspc 0.1.x | Use the 'tauri' feature on rspc |
Unsupported. Upgrade to rspc 0.2.x |
| rspc 0.2.x | Use rspc_tauri crate |
Use rspc_tauri2 |
To import it add the following to your Cargo.toml:
rspc-tauri2 = { git = "https://github.com/specta-rs/tauri2", rev = "1a41c9217ccec1814e3e4c5e343bcc9739efab40" }Then follow the rspc docs but replace rspc_tauri with rspc_tauri2.
You will also need to use @rspc/tauri import from here which is not published to npm.
I would highly recommend using pnpm and copying the patch from rspc_example/patches/@rspc__tauri@0.2.0.patch and then copying the patches section from the package.json.
You can follow the documentation here for Tauri v2 support.
| tauri1 | tauri2 | |
|---|---|---|
| specta1 | Via 'tauri' feature on specta |
Unsupported. Upgrade to specta2 |
| specta2 | Unsupported. Upgrade to Tauri2 | Via 'specta' feature on tauri |
Previously Specta had a tauri feature on specta for functions support. This function support is what powers Tauri Specta.
You can't actually have Tauri and Tauri v2 in the same Cargo workspace.
This is due to Tauri depending on C/C++ libraries such as Webkit which link against shared libraries. Cargo flags the potential for the same shared library to be linked twice and bails out.
This would make sense at a crate level but the resolver isn't super smart and bails out at a workspace level.
You will see an error like the following if you hit this:
error: failed to select a version for `webkit2gtk-sys`.
... required by package `webkit2gtk v2.0.1`
... which satisfies dependency `webkit2gtk = "=2.0.1"` of package `tauri v2.0.0-beta.13`
... which satisfies dependency `tauri = "=2.0.0-beta.13"` of package `rspc-tauri2 v0.0.1 (/Users/oscar/Desktop/rspc-014/crates/tauri2)`
versions that meet the requirements `^2.0.1` are: 2.0.1
the package `webkit2gtk-sys` links to the native library `web_kit2`, but it conflicts with a previous package which links to `web_kit2` as well:
package `webkit2gtk-sys v0.18.0`
... which satisfies dependency `ffi = "^0.18"` of package `webkit2gtk v0.18.2`
... which satisfies dependency `webkit2gtk = "^0.18.2"` of package `tauri v1.6.1`
... which satisfies dependency `tauri = "=1.6.1"` of package `rspc-tauri v0.0.1 (/Users/oscar/Desktop/rspc-014/crates/tauri)`
Only one package in the dependency graph may specify the same links value. This helps ensure that only one copy of a native library is linked in the final binary. Try to adjust your dependencies so that only one package uses the `links = "web_kit2"` value. For more information, see https://doc.rust-lang.org/cargo/reference/resolver.html#links.
