Struct Client 

pub struct Client { /* private fields */ }

A ringline-native Ping client wrapping a single connection.

Client::new(conn) creates a zero-overhead client with no callbacks or metrics. Use Client::builder(conn) to configure per-request callbacks, kernel timestamps, and built-in histogram tracking.

Implementations

impl Client

pub fn new(conn: ConnCtx) -> Self

Create a new client wrapping an established connection.

No callbacks, no metrics, no kernel timestamps — zero overhead.

pub fn builder(conn: ConnCtx) -> ClientBuilder

Create a builder for a client with per-request callbacks.

pub fn conn(&self) -> ConnCtx

Returns the underlying connection context.

pub fn metrics(&self) -> Option<&ClientMetrics>

Returns a reference to the built-in metrics, if enabled.

pub fn metrics_mut(&mut self) -> Option<&mut ClientMetrics>

Returns a mutable reference to the built-in metrics, if enabled.

pub async fn ping(&mut self) -> Result<(), Error>

Send a PING and wait for a PONG response.
