Struct Inputs 

pub struct Inputs<'a> {
    pub repository: &'a Repository,
    pub share: Option<&'a Share>,
    pub index: Option<&'a Index>,
    pub registry: Option<&'a CapabilityRegistry>,
    pub policy: Option<&'a LoadedPolicy>,
}

What the resolver may read. A fast resolution carries no index and no registry; a full one carries both, and the presence of the index is what makes it full.

Fields

repository: &'a Repository

The repository, already discovered.

share: Option<&'a Share>

The distribution directory, when it was located.

index: Option<&'a Index>

The index, in a full resolution.

registry: Option<&'a CapabilityRegistry>

The registry, in a full resolution.

policy: Option<&'a LoadedPolicy>

The policy, when the caller has already read it. The resolver reads it itself when this is None, which is what every caller that needs nothing else from it does.

It is here for the one caller that does: majordomus env enter asks the policy whether entry ensures a runtime, and then resolves a snapshot whose provider projections come out of the same file. Two reads of one canonical file inside one invocation is what project.hot-path-reads-once is about, and this is the hot path by definition — it runs on every cd.
