Struct Anchor 

pub struct Anchor {
    pub file: String,
    pub side: String,
    pub line: u32,
    pub end_line: u32,
    pub offset: i32,
    pub span: u32,
    pub hunk_digest: String,
    pub line_text: String,
    pub end_line_text: String,
}

Fields

file: String

side: String

“old” | “new”

line: u32

First anchored line, in file coordinates. DERIVED — offset is what survives a regeneration, and this is recomputed from it.

end_line: u32

Last anchored line. Equal to line for a single-line anchor; 0 on a record written before ranges existed, which reads as “just line”.

offset: i32

Lines from the hunk’s start to line. Signed: a reader can annotate a context line, and context sits on both sides of a hunk.

This, not line, is what the anchor is really made of. The digest fixes the hunk’s CONTENT, so a hunk that moved in the file still holds the same line at the same offset — while its absolute line number did not survive the move. A record written before offsets existed has 0, which lands it on the hunk’s first line: exactly where it used to.

span: u32

Lines the anchor spans past offset. 0 is a single line.

hunk_digest: String

line_text: String

The anchored line’s text — the fuzzy re-anchor key.

end_line_text: String

The last anchored line’s text, for the same job at the range’s far end.

Implementations

impl Anchor

pub fn at(&self) -> String

Where this is, as a reader writes it: src/app.rs:47-52.

pub fn line_span(&self) -> String

The lines this annotates, as a reader writes them: 47, or 47-52.

One place decides it, because end_line is 0 on a record written before ranges existed and every consumer would otherwise have to know that.
