Google Drive Text Embedding (Rust)

Rust port of examples/gdrive_text_embedding.

Pipeline:

Google Drive files -> markdown chunks -> all-MiniLM-L6-v2 embeddings -> Postgres/pgvector

Prerequisites

• Postgres with pgvector
• A Google Cloud service account that can read the target Drive folders
• Environment variables:

export POSTGRES_URL="postgres://cocoindex:cocoindex@localhost/cocoindex"
export GOOGLE_SERVICE_ACCOUNT_CREDENTIAL="/path/to/service-account.json"
export GOOGLE_DRIVE_ROOT_FOLDER_IDS="folder_id_1,folder_id_2"

Run

Index:

cargo run -- index

Query:

cargo run -- query "what is self-attention?"

The Rust source currently uses Drive file id as the mount_each key to avoid duplicate-name collisions. The stored filename is the path relative to the configured Drive root folder, matching the Python example's path-oriented metadata.
