Fields§
§name: &'a strField 1: name

key_columns: RepeatedView<'a, u32>Indices into Table.columns that make up the index key, in sort order.
Field 3: key_columns
cover_columns: RepeatedView<'a, u32>Additional column indices stored in the index payload so point lookups through this index don’t need a base-row fetch (“covered” columns).

buf into this view (proto merge semantics):
repeated fields append, singular fields last-wins, singular message
fields merge recursively. Read moreSource§impl<'__a> Serialize for IndexView<'__a>
Serializes this view as protobuf JSON.
impl<'__a> Serialize for IndexView<'__a>
Serializes this view as protobuf JSON.
Implicit-presence fields with default values are omitted, required
fields are always emitted, explicit-presence (optional) fields are
emitted only when set, bytes fields are base64-encoded, and enum
values are their proto name strings.
This impl uses serialize_map(None) because the number of emitted
fields depends on default-omission rules; serializers that require
known map lengths (e.g. bincode) will return a runtime error.
Use the owned message type for those formats.
