include! bindings.rs

[pragmatrix]

Now that IntelliJ Rust has landed support for include!(concat!(env!("OUT_DIR"), ..)) it's time to prepare a PR that generates the bindings.rs file in the output directory and includes it from skia-bindings/src/lib.rs.

To enable code insight in IntelliJ based IDEs, the experimental feature org.rust.cargo.fetch.out.dir has to be enabled. More information is available from the IntelliJ Rust team.

I'll keep this PR open and unmerged until both IntelliJ Rust and Rust Analyzer are officially resolving OUT_DIR through the build script output as a faster alternative compared to cargo --build-plan that is currently in use.

Closes #10

Here an update regarding the blockers for the PR:

Rust Analyzer

has full support, but it must be enabled in the VSCode settings first:

{
    "rust-analyzer.cargoFeatures.loadOutDirsFromCheck": true,
}

but Goto Definition is not yet working correctly:

rust-lang/rust-analyzer#3767

IntelliJ Rust

org.rust.cargo.fetch.out.dir must be set in "Experimental Features" (available through the Actions menu).

Otherwise it seems to work fine, so no blockers for IntelliJ Rust anymore.

The rust-analyzer team closed rust-lang/rust-analyzer#3767.

Closed in favor of #798
