Struct A2aServer 

pub struct A2aServer;

Available on crate features a2a-v1 and server only.

Convenience wrapper for quickly starting an A2A-capable server.

Provides two entry points:

• A2aServer::quick_start for zero-config usage
• A2aServer::builder for custom configuration

Example

use adk_server::a2a::convenience::A2aServer;
use std::sync::Arc;

let app = A2aServer::quick_start(my_agent);
let listener = tokio::net::TcpListener::bind("0.0.0.0:8080").await?;
axum::serve(listener, app).await?;

Implementations

impl A2aServer

pub fn quick_start(agent: Arc<dyn Agent>) -> Router

Create an A2A-ready Axum app with sensible defaults.

Uses an in-memory session service, binds to http://localhost:8080, enables streaming, and auto-generates the agent card from agent metadata.

Arguments

• agent - The agent to expose via A2A protocol

Example

use adk_server::a2a::convenience::A2aServer;
use std::sync::Arc;

let app = A2aServer::quick_start(my_agent);
let listener = tokio::net::TcpListener::bind("0.0.0.0:8080").await?;
axum::serve(listener, app).await?;

pub fn builder() -> A2aServerBuilder

Create a builder for custom A2A server configuration.

Example

use adk_server::a2a::convenience::A2aServer;
use std::sync::Arc;

let server = A2aServer::builder()
    .agent(my_agent)
    .bind_addr("0.0.0.0:9090")
    .streaming(false)
    .build()?;

server.serve().await?;
