Enum Resolution 

pub enum Resolution {
    One {
        node: NodeId,
        path: String,
    },
    UnknownBranch,
    AmbiguousBranch {
        paths: Vec<String>,
    },
    UnknownPort {
        branch: String,
    },
    AmbiguousPort {
        paths: Vec<String>,
    },
}

The answer to “does Branch::port name exactly one face?”. “Branch::port 是否恰好命名一个注册面？“的答案。

Every failure is a distinct variant carrying the facts a diagnostic needs (which paths collided), so a caller never has to re-derive them. 每种失败都是独立的变体，并携带诊断所需的事实（哪些路径冲突），因此调用方不需要自己重新 推导。

Variants

One

Exactly one face provides the port inside the branch. 分支内恰好有一个注册面提供该端口。

Fields

node: NodeId

The providing face. 提供该端口的注册面。

path: String

Its logical path. 它的逻辑路径。

UnknownBranch

No node in the tree carries that branch handle. 树中没有任何节点携带该分支句柄。

AmbiguousBranch

Several nodes carry that branch handle, so the reference is ambiguous before the port is even considered. 多个节点携带该分支句柄，因此还没看端口，引用就已经有歧义。

Fields

paths: Vec<String>

Every carrier, by logical path. 每个携带者，按逻辑路径列出。

UnknownPort

The branch exists; nothing in it provides that port. 分支存在，但其中没有东西提供该端口。

Fields

branch: String

The branch handle that was searched. 被搜索的分支句柄。

AmbiguousPort

Several faces inside the branch provide that port. 分支内有多个注册面提供该端口。

Fields

paths: Vec<String>

Every provider, by logical path. 每个提供者，按逻辑路径列出。
