hyper-custom-cert 0.3.6

A small, ergonomic HTTP client wrapper around hyper with optional support for custom Root CAs and a dev-only insecure mode for self-signed certificates.
Documentation
//! Integration tests for rustls features
//!
//! These tests verify that the library works correctly with the rustls feature
//! enabled, including custom CA certificate support and certificate pinning.
