Struct MemberPin 

pub struct MemberPin {
    pub member: String,
    pub hub: String,
    pub rev: Option<String>,
    pub via: Option<String>,
}

One member’s version pin: the revision of a hub it deploys (ADR-0009 step 8).

Why it names its hub

A pin is hub-relative, and since #623 a workspace is a snowflake rather than a star: a project can be a spoke of one project and the hub of others, so “the hub version this member pins” has no single referent. infra pins chart, and chart pins app. Naming the hub is what lets a reader follow the chain instead of guessing which end of it a bare revision belongs to.

Fields

member: String

The member doing the pinning — the spoke.

hub: String

The workspace member whose version is pinned — this member’s parent in the dependency graph, not necessarily the workspace’s busiest node.

rev: Option<String>

The hub git revision pinned: a submodule sha, or an image tag resolved to a hub ref. None when the member depends on hub but declares no version this tool can resolve.

None is a finding, not an absence of one — see the module’s rendering of it, and issue #505, which established that “asked and found nothing” must not render identically to “never asked”.

via: Option<String>

Where the pin was read from (submodule vendor/app, image acme/app:1.4.0). None exactly when rev is.
