Tauri 2

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.

rspc

	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

Using rspc_tauri2

To import it add the following to your Cargo.toml:

rspc-tauri2 = { git = "https://github.com/specta-rs/tauri2", rev = "a605fbb7b77ba55ca310c20e2475fddb05fbc969" }

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/@[email protected] and then copying the patches section from the package.json.

Tauri Specta

You can follow the documentation here for Tauri v2 support.

Specta

	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.

FAQ?

Why a whole repository for this?

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.
