rvf-import provides both a library API and a CLI binary for importing vector data from common formats into .rvf files. Supports automatic ID generation, metadata extraction, and batch ingestion.

Supported Formats

Format	Extension	Features
JSON	`.json`	Configurable ID/vector/metadata field names
CSV	`.csv`	Header-based column mapping, configurable delimiter
NumPy	`.npy`	Direct binary array loading, auto-dimension detection

Library Usage

use rvf_import::json::{parse_json_file, JsonConfig};

let config = JsonConfig {
    id_field: "id".into(),
    vector_field: "embedding".into(),
    ..Default::default()
};
let records = parse_json_file(Path::new("vectors.json"), &config)?;

CLI Usage

rvf-import --input data.npy --output vectors.rvf --format npy --dimension 384
rvf-import --input data.csv --output vectors.rvf --format csv --dimension 128
rvf-import --input data.json --output vectors.rvf --format json

Tests

cargo test -p rvf-import
