Crate echo_macros 

echo-macros

Procedural macros for the echo-agent framework.

Macros

Macro	Generates	Description
#[tool]	Tool impl	Auto-generates params struct, JSON Schema, and Tool trait impl from an async fn
#[callback]	AgentCallback impl	Generates lifecycle callbacks from an impl block
#[guard]	Guard impl	Content filtering guard from an async fn
#[handler]	HumanLoopHandler impl	Human-in-the-loop handler from an impl block
#[compressor]	ContextCompressor impl	Context compression strategy from an async fn
#[permission_policy]	PermissionPolicy impl	Tool permission policy from an async fn
#[audit_logger]	AuditLogger impl	Audit logging backend from an impl block

Quick Example

use echo_agent::tool;

#[tool(name = "add", description = "Add two numbers")]
async fn add(a: f64, b: f64) -> Result<ToolResult> {
    Ok(ToolResult::success(format!("{}", a + b)))
}

Most users should import these macros via echo_agent::prelude::* or use echo_agent::{tool, callback, guard, handler}; rather than depending on echo_macros directly.

Attribute Macros

audit_logger

Generate an AuditLogger implementation from an impl block.

callback

Generate an AgentCallback implementation from an impl block, overriding only the methods you define.

compressor

Generate a ContextCompressor implementation from an async function.

guard

Generate a Guard implementation from an async function.

handler

Generate a HumanLoopHandler implementation from an impl block.

permission_policy

Generate a PermissionPolicy implementation from an async function.

tool

Generate a Tool implementation from an async function, auto-creating the parameter struct and JSON Schema.
