by [`SnapshotProducer`] to customize snapshot creation
+<a href=#40 id=40 data-nosnippet>40</a>/// based on the type of operation
being performed (e.g., `Append`, `Overwrite`, `Delete`, etc.).
+<a href=#41 id=41 data-nosnippet>41</a>/// Each operation type implements this
trait to specify:
+<a href=#42 id=42 data-nosnippet>42</a>/// - Which operation type to record in
the snapshot summary

should be included in the new snapshot

+<a href=#49 id=49 data-nosnippet>49</a>///
+<a href=#50 id=50 data-nosnippet>50</a>/// 1. **Operation Type Recording**:
The `operation()` method determines which operation type
+<a href=#51 id=51 data-nosnippet>51</a>/// (e.g., `Operation::Append`,
`Operation::Overwrite`) is recorded in the snapshot summary.
+<a href=#52 id=52 data-nosnippet>52</a>/// This metadata helps track what

+<a href=#54 id=54 data-nosnippet>54</a>/// 2. **Manifest File Selection**: The
`existing_manifest()` method determines which existing
+<a href=#55 id=55 data-nosnippet>55</a>/// manifest files from the current
snapshot should be carried forward to the new snapshot.
+<a href=#56 id=56 data-nosnippet>56</a>/// For example:

typically includes all existing manifests plus new ones

exclude manifests for partitions being overwritten
+<a href=#59 id=59 data-nosnippet>59</a>///
+<a href=#60 id=60 data-nosnippet>60</a>/// 3. **Delete Entry Processing**: The
`delete_entries()` method is intended for future delete
