Struct KnownEntry 

pub struct KnownEntry {
    pub object: ObjectId,
    pub parent: ObjectId,
}

What: One candidate whose content a parent already holds: the object and the first parent that holds it. #[derive(...)] generates cloning, debug printing and ==. Why: The skip is a decision, and a decision is only checkable when its inputs are kept.

In TS you’d write (pseudocode):

type KnownEntry = { object: ObjectId; parent: ObjectId };

Fields

object: ObjectId

The candidate’s blob.

parent: ObjectId

The commit whose tree holds the blob.

Implementations

impl KnownEntry

What: impl KnownEntry { ... } attaches the record of the decision. Why: One wording for the decision, so a log line always carries the same inputs.

In TS you’d write (pseudocode):

class KnownEntry { describe(displayPath: string): string }

pub fn describe(&self, display_path: &str) -> String

What: The decision as one line of text. &str is the pathname as the scanner masks it. Why: The pathname is shown masked because a pathname may hold a secret; the blob and the parent are object names.

In TS you’d write (pseudocode):

describe(displayPath: string): string
