Struct NoOpClient 

pub struct NoOpClient { /* private fields */ }

A no-op HTTP client that always fails with an error.

This client is useful for testing VCR in replay mode to ensure that no real HTTP requests are made. Any attempt to send a request will result in an error.

Usage

use http_client_vcr::{VcrClient, VcrMode, NoOpClient};
use http_client::HttpClient;
use http_types::{Request, Method, Url};

// Ensure no real HTTP requests can be made
let vcr_client = VcrClient::builder("fixtures/test.yaml")
    .inner_client(Box::new(NoOpClient::new()))
    .mode(VcrMode::Replay) // Only replay from cassette
    .build()
    .await?;

// This will work if the request is in the cassette
let request = Request::new(Method::Get, Url::parse("https://example.com")?);
let response = vcr_client.send(request).await?;

// If not in cassette, VCR will return an error before reaching NoOpClient
// If somehow a request reaches NoOpClient, it will panic with a clear message

Implementations

impl NoOpClient

pub fn new() -> Self

Create a new NoOpClient with a default error message.

pub fn with_message(message: impl Into<String>) -> Self

Create a NoOpClient with a custom error message.

pub fn panicking() -> PanickingNoOpClient

Create a NoOpClient that panics instead of returning an error. This is useful for catching unexpected HTTP requests during development.
