Struct HttpClient 

pub struct HttpClient { /* private fields */ }

HTTP client for network operations

TLS crypto provider

When built with the reqwest feature, HttpClient::new auto-calls HttpClient::init, which builds a reqwest::Client eagerly – this constructs rustls’ ClientConfig inside .build() even for a client that never issues an HTTPS request. Since the workspace’s reqwest dependency uses rustls-no-provider (no aws-lc-rs/ring bundled – see the “PURE RUST BLOCKER (reqwest)” note in the workspace root Cargo.toml), this crate installs the pure-Rust OxiTLS provider (oxitls-rustcrypto-provider, COOLJAPAN’s RUSTSEC-2026-0104-fixed fork of the abandoned upstream rustls-rustcrypto 0.0.2-alpha, resolved under the rustls-rustcrypto name) as the process-default rustls CryptoProvider automatically, right before the first client is constructed – unless the application has already installed a provider of its own. Applications that want a different provider (e.g. a C-linked aws-lc-rs/ring one) simply call rustls::crypto::CryptoProvider::install_default(...) before the first use of SciRS2 networking; an existing process default is never overridden.
