Macro tool_executor_forward 

macro_rules! tool_executor_forward {
    ($inner:ident) => { ... };
}

Forwards the four mechanical capability methods of ToolExecutor — the checkpoint trio and is_tool_speculatable — to self.$inner.

Use inside impl ToolExecutor for YourWrapper where $inner is the field name (an identifier, not an expression — macro hygiene forbids capturing self at item position) of a field whose type implements ToolExecutor.

The two policy methods, requires_confirmation and execute_tool_call_confirmed, are intentionally not emitted by this macro — wrappers that gate on confirmation or checkpoint policy must implement those two explicitly, so the compiler forces every wrapper author to make a deliberate decision about them instead of inheriting one silently.

Examples

use zeph_tools::{ToolExecutor, ToolCall, ToolOutput, ToolError};

struct PassThrough<T> {
    inner: T,
}

impl<T: ToolExecutor> ToolExecutor for PassThrough<T> {
    async fn execute(&self, response: &str) -> Result<Option<ToolOutput>, ToolError> {
        self.inner.execute(response).await
    }

    fn requires_confirmation(&self, call: &ToolCall) -> bool {
        self.inner.requires_confirmation(call)
    }

    async fn execute_tool_call_confirmed(
        &self,
        call: &ToolCall,
    ) -> Result<Option<ToolOutput>, ToolError> {
        self.inner.execute_tool_call_confirmed(call).await
    }

    zeph_tools::tool_executor_forward!(inner);
}
