Struct ParsedIndexAttribute 

pub struct ParsedIndexAttribute {
    pub fields: Vec<String>,
    pub using: Option<String>,
    pub opclass: Option<String>,
}

The parsed shape of an @@index([...], using: ..., opclass: "...") attribute.

using/opclass are carried through verbatim — not validated against a closed list of Postgres access methods/operator classes. Per docs/design/extensions.md §2/§6, the framework deliberately avoids hardcoding pgvector’s own index types as the only supported similarity-search backend, so any syntactically valid identifier is accepted here and left for Postgres itself to accept or reject at CREATE INDEX time.

Fields

fields: Vec<String>

Local field names, in declaration order — the index’s column order.

using: Option<String>

using: <method> — e.g. ivfflat, hnsw, gin. None means no access method was named, which renders as a plain CREATE INDEX with Postgres’s own default (btree) left implicit.

opclass: Option<String>

opclass: "<name>" — applied to every column listed in fields. None leaves each column’s default operator class in place.
