manticoresoftware/manticoresearch-rust: Rust client for Manticore Search

This API client was generated by the OpenAPI Generator project. By using the openapi-spec from a remote server, you can easily generate an API client.

Put the package under your project folder in a directory named manticoresearch and add the following to Cargo.toml under [dependencies]:

manticoresearch = { path = "./manticoresearch" }

use std::sync::Arc;
use std::collections::HashMap;
use serde_json;
