Rust environment support

[sanketsudake]

Is your feature request related to a problem? Please describe.
We would like to enabled Rust language as one of the fission environments.

Describe the solution you'd like
As a Fission user I should be able to run/deploy functions written using Rust language.

Describe alternatives you've considered

Help Wanted:
I try to set an environment for the rust-lang. Now I have some trouble with the build.sh from the builder. When it runs for the package creation it looks like that shell-script is faster than the cargo build command. And then directory of the env var DEPLOY_PKG isn't anymore available. Hopefully someone can help me or point me to the right direction.

See the output from the builder build.sh:

Name:        fission-rust-handler-7bf3c9dc-9c18-461f-a28f-1743b2a23f71
Environment: rust-env
Status:      failed

Hey, @Algorab would it be possible to share your source? Maybe I can give it try with local build.

[Algorab]

Hi @sanketsudake, you can find the current state of the project here fission rust

[Algorab]

After some more debugging I have found out that:
the source-dir " /packages/fission-rust-handler-7bf3c9dc-9c18-461f-a28f-1743b2a23f71-xvznrm" is available in the builder for the function. The deploy-dir "/packages/fission-rust-handler-7bf3c9dc-9c18-461f-a28f-1743b2a23f71-xvznrm-yznpts" doesn't exists. Should it be normally there, have I it to create?

[AdarshdeepCheema]

I am also hitting the same issue @sanketsudake
can u please check what is wrong here ?

[AdarshdeepCheema]

I have 3 files in the zip

package.json
package-lock.json
build.sh

I am running fission package create --spec --sourcearchive src-pkg.zip --env nodejs --name ap-pkg --buildcmd "./build.sh" --envNamespace fission --pkgNamespace=controlplane
This only happens when I use the --buildcmd "./build.sh"
Error uploading deployment package: Internal error - error archiving zip file: failed to zip file: stat /packages/ap-pkg-mxnp60-sjljw7: no such file or directory

[Stradivario]

Any progress on this ?
