Struct Diff 

pub struct Diff {
    pub patch: Value,
    pub forced_snapshot: bool,
}

The result of diffing a value into an RFC 7396 merge patch.

Fields

patch: Value

A merge patch that transforms the old value into the new one.

forced_snapshot: bool

Set when the change can’t be faithfully expressed as a merge patch, so the caller should publish a full snapshot instead. This happens when a value is set to JSON null, which merge patch reads as a key deletion, or when the root is not an object. Arrays are fine: merge patch replaces them wholesale, which is still typically smaller than a full snapshot.
