Enum InferencePlan 

pub enum InferencePlan {
    Search {
        backend: String,
        index_name: String,
        query_param_name: String,
        query_literal: Option<String>,

    },
}

Pre-execution inference plan — set when the query requires an external model call before the SQL can be executed. Python switches on the variant.

Variants

Search

fts::search with a remote backend (OpenSearch or Meilisearch). Python fetches (id, score) pairs from the backend, then injects them as __deferred_ids__ / __deferred_scores__ params and runs sql against Postgres.

Fields

backend: String

Remote backend identifier: "opensearch" or "meilisearch".

index_name: String

Remote index name.

query_param_name: String

Name of the user’s query-text param; empty string when an inline literal.

query_literal: Option<String>

Inline literal query text.

size: Option<usize>

Requested result size (limit), if known at compile time.

Embedding

vector::search(TypeName, query := $text) text overload. Python embeds the text via the configured model provider, then injects the resulting vector as __deferred_vec__ and runs sql against Postgres.

Fields

model_name: String

Embedding model identifier from the schema, e.g. "mistral-embed".

type_name: String

Qualified type name for provider lookup, e.g. "default::Product".

index_name: Option<String>

Vector index name for provider lookup (None = default index).

query_param_name: String

Name of the user’s query := param; empty string when an inline literal.

query_literal: Option<String>

Inline literal query text.
