Enum IndexEntry 

pub enum IndexEntry {
    Set {
        mode: String,
        oid: String,
        path: Vec<u8>,
    },
    Remove {
        path: Vec<u8>,
    },
}

One record to feed a scratch index.

Owned rather than borrowed: a text file’s oid is produced by ObjectWriter::write_blob inside the staging loop and would not outlive a borrow. One allocation per changed file is free next to the subprocess it is about to be piped into.

Implementations

impl IndexEntry

pub fn from_staged( staged: Staged<'_>, path: Vec<u8>, write: impl FnOnce() -> Result<String, EngineError>, ) -> Result<IndexEntry, EngineError>

The index record a staging decision implies.

Remove and Recorded need nothing beyond the decision. Apply needs content written, and only the caller knows how — from a blob read fresh or one it has memoised — so write is asked for the oid then, and never otherwise. The three tree builders used to spell all three arms out for themselves, and agreed only by inspection.
