Crate openmodex 

OpenModex SDK for Rust

Official Rust SDK for the OpenModex API.

OpenModex is a unified API gateway for accessing multiple LLM providers through a single OpenAI-compatible interface.

Quick Start

use openmodex::{OpenModex, ChatCompletionRequest, ChatMessage, Error};

#[tokio::main]
async fn main() -> Result<(), Error> {
    let client = OpenModex::new("omx_sk_...")?;

    let response = client.chat().completions().create(
        ChatCompletionRequest::new("gpt-4o")
            .message(ChatMessage::user("Hello!"))
            .temperature(0.7)
    ).await?;

    println!("{}", response.choices[0].message.as_ref()
        .and_then(|m| m.content.as_deref())
        .unwrap_or(""));

    Ok(())
}

Streaming

use openmodex::{OpenModex, ChatCompletionRequest, ChatMessage, Error};
use futures::StreamExt;

#[tokio::main]
async fn main() -> Result<(), Error> {
    let client = OpenModex::new("omx_sk_...")?;

    let mut stream = client.chat().completions().create_stream(
        ChatCompletionRequest::new("gpt-4o")
            .message(ChatMessage::user("Tell me a story"))
    ).await?;

    while let Some(chunk) = stream.next().await {
        let chunk = chunk?;
        if let Some(content) = chunk.choices.first()
            .and_then(|c| c.delta.content.as_ref())
        {
            print!("{content}");
        }
    }

    Ok(())
}
