FunctionServer

Struct FunctionServer 

Source
pub struct FunctionServer { /* private fields */ }
Expand description

Unified server for hosting serverless functions.

§Examples

use serverless_fn::server::{FunctionServer, ServerConfig};

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error + Send + Sync>> {
    // Method 1: Using builder pattern
    FunctionServer::new()
        .host("0.0.0.0")
        .port(3000)
        .start()
        .await?;

    // Method 2: Using custom config
    let config = ServerConfig::new().host("0.0.0.0").port(3000);
    FunctionServer::with_config(config)
        .start()
        .await?;

    Ok(())
}
