I think this is the only big outstanding question on this PR. How exactly do we want to access components outside of the orchestrator prior to validation?

Whats the alternative? What are your concerns with this approach?

I can think of a couple of alternatives:

Add getter functions to RuntimeComponentsBuilder, or

Create a OptionalRuntimeComponents struct that is analog to RuntimeComponents, but where creation doesn't do validation, and all the components in it are wrapped in Option. The RuntimeComponentsBuilder would have a build_optional function to create this.

The current approach is limited to time/sleep. In the future, some other non-time related component may be needed outside of the orchestrator. Given that, I think these alternatives would be better, but then it's just a matter of picking between them.

I don't think what you have is a one way door so I'm not too concerned.

Overall looks great! Few questions and some discussion.

Still going through the PR, but looks great so far. One clarifying question. .customize and .wait_XXX on a fluent builder cannot be used together, i.e. the following is not supported?

client
    .operation()
    .customize()
    .config_override(...)
    .wait_until_XXX
    ...

Excellent work! In codegen diff, I see the doc on a waiter's fluent builder look like

impl ImageExistsFluentBuilder {
    /// Creates a new `DescribeImages`.
    pub(crate) fn new(handle: ::std::sync::Arc<crate::client::Handle>) -> Self {
        Self {
            handle,
            inner: ::std::default::Default::default(),
        }
    }

It says /// Creates a new DescribeImages but not /// Creates a new ImageExistsFluentBuilder or /// Creates a new ImageExists. Is that expected?

I opted to not support this yet without better understanding the use-case for it. It won't be hard to add if a good reason comes up.

No, this is a bug. Fixed in 8a3d012
