openbao 0.4.0

//! Secure, typed, async Rust SDK for OpenBao.
//!
//! This crate is intentionally conservative:
//!
//! - unsafe Rust is forbidden;
//! - tokens are stored as [`secrecy::SecretString`];
//! - HTTPS is required by default;
//! - OpenBao API URLs are assembled with structured URL path segments;
//! - authentication state is represented in the type system.
//!
//! The public API covers environment-based client construction, AppRole login,
//! direct token auth, token lifecycle helpers, KV v1/v2, Transit, system
//! health/seal status, dev-only bootstrap, mount management, audit devices,
//! safe exact lease helpers, plugin catalog operations, and raw JSON calls for
//! advanced users.
//!
//! Secret request payloads are serialized through a zeroizing intermediate
//! buffer before handoff to `reqwest`. The HTTP stack still owns a normal body
//! buffer after that handoff, and TLS, kernel, allocator, and device buffers
//! can retain transient copies outside this crate's control. Treat Transit
//! plaintext and other request-body secret material as process-resident during
//! the request lifecycle.
