Crate rustls_config_stream 

rustls::ServerConfig provider backed by an async stream.

This module exposes a ServerConfigProvider that holds the “current” TLS server configuration and updates it whenever a new config arrives from a user-supplied stream (see ServerConfigStreamBuilder).

The background task performs exponential backoff (10ms -> 10s, doubling) when the stream fails, and attempts to re-create the stream via the builder. Call ServerConfigProvider::get_config whenever you need an Arc<ServerConfig>.

Overview

• Implement ServerConfigStreamBuilder to produce a stream of fresh ServerConfig instances (e.g., reading from disk, a secret store, or watching a certificate manager).
• Start the provider with ServerConfigProvider::start.
• Use ServerConfigProvider::get_config wherever you need the current config (e.g., inside an acceptor loop).
• Optionally monitor liveness via ServerConfigProvider::stream_healthy.

Tracing

If the tracing feature is enabled, the provider will emit diagnostics (debug/info/error) about updates and reconnection attempts.
