rCOMM7c865a63f7ec: [services][blob] Introduce S3 primitives
Summary

Introduced two S3 primitives:

  • S3 path - a convenience struct to store object and bucket name. See C++ counterpart
  • Multipart upload session - needed for Put requests to upload large blobs to S3. See C++ counterpart. Its implementation is added in the subsequent diff.

Depends on D5678

Test Plan

Added two simple unit tests for S3Path.

Would be great if @varun could review all of @bartek's work on the blob service in Rust, given it touches AWS. @bartek, if @varun doesn't respond on diffs feel free to ping him on Comm

It is almost never a good idea to panic in the code. We should handle errors more gracefully, by e.g. returning Result.

29 ↗(On Diff #18587)

It's usually more convenient to use format! macro

52 ↗(On Diff #18587)

You can probably use a shorthand: Result<(), anyhow::Error> should work the same as Result<()>

63 ↗(On Diff #18587)

It might be a good idea to add a test with invalid path

Why do we use triple slashes?

Rustdoc - IDE displays a pretty description when you hover on a function name.

Counterpart of

/**
 * Some description
 */

in JS

17 ↗(On Diff #18587)

I panicked, because I'm sick of this Option/Result unwrapping hell. But in this case, this shouldn't be a problem so I'll change that

52 ↗(On Diff #18587)

Yes, you're right. I'll change that everywhere

63 ↗(On Diff #18587)

Yes, I'll add it

  • Used short form of anyhow::Result
  • The S3Path::from_full_path now returns Result
  • Used format! macro
  • Added a unit test for invalid path

I think Rust now supports let-else statements which might feel more ergonomic to you for unpacking Results and Options

Yes, since 1.65 (we're using 1.61 IIRC) - there are tasks for this: ENG-2002, ENG-2003
