Module envoy_sdk::extension::access_logger

Envoy Access Logger extension.

Creating a new Access Logger extension using Envoy SDK consists of the following steps:

1. Implement AccessLogger trait to define core logic of your extension
2. Register your extension on WebAssembly module start up

Examples

Basic AccessLogger:

use envoy::extension::AccessLogger;

/// My very own `AccessLogger`.
struct MyAccessLogger;

impl AccessLogger for MyAccessLogger {
    fn name() -> &'static str { "my_access_logger" }
}

Registration of MyAccessLogger on start up:

use envoy::extension::{entrypoint, Module, Result};

entrypoint! { initialize } // put initialization logic into a function to make it unit testable

fn initialize() -> Result<Module> {
    Module::new()
        .add_access_logger(|_instance_id| Ok(MyAccessLogger))
}

Traits

AccessLogger	An interface of the Envoy Access Logger extension.
ConfigureOps	An interface for operations available in the context of on_configure invocation.
DrainOps	An interface for acknowledging Envoy that AccessLogger has been drained.
LogOps	An interface for accessing data of the HTTP stream or TCP connection that is being logged.
