Struct Snapshot 

pub struct Snapshot(/* private fields */);

The files under a root at one moment, to diff against a later one.

Taken one of two ways, and compared only with one taken the same way:

• in a git work tree on this machine that does not ignore the root, as a git tree written with a private index and object directory, so the user’s repository is never written to;
• elsewhere, as a scan of what Workspace::files lists, with each file’s size, change time and hash.

Either way, the content of each file up to MAX_FILE_BYTES is kept when the snapshot was taken with somewhere to keep it (Taking::keep). The files git or files leaves out (ignored, hidden, target) are not in it, unless named in Taking::also.

Implementations

impl Snapshot

pub fn changes_since(&self, earlier: &Snapshot) -> Result<Vec<FileChange>>

What changed from earlier to this snapshot, in path order: files created, modified and deleted, with the FileState of each side. A snapshot that kept content also gives each change’s diff and line counts; a scan that kept none gives a modified file’s states only.

Errors

When the two were taken different ways, or git fails.

pub fn content(&self, path: &Path) -> Option<Result<Vec<u8>>>

The bytes the file path held when this snapshot was taken, when it kept content (Taking::keep); None for a scan that kept none.
