不确定 PRJ_FILE_STATE_HYDRATED_PLACEHOLDER 文档的含义

Not sure what PRJ_FILE_STATE_HYDRATED_PLACEHOLDER documentation means

我开始使用 Projected File system,但我不确定我是否正确阅读了文档。 PRJ_FILE_STATE_HYDRATED_PLACEHOLDER。 说

The item is a hydrated placeholder, i.e., the item's content has been written to disk.

对我来说,这听起来像是文件内容(不是元数据)被写入磁盘。
然而,还有 PRJ_FILE_STATE_FULL 听起来也像是缓存了完整的数据(元数据 + 文件内容)。

我认为 PRJ_FILE_STATE_HYDRATED_PLACEHOLDER 实际上意味着

[...] the item's metadata has been written to dist.

有人可以证实吗?

我在 documentation 中找到了更详细的另一部分:

Hydrated placeholder

For files: The file’s content and metadata have been cached to the disk. Also referred to as a "partial file".

For directories: A directory that was created on disk as a placeholder never becomes a hydrated placeholder directory. This allows the provider to add or remove items from the directory in its backing store and have those changes be reflected in the local cache.
