pub fn install_default_crypto_provider()Expand description
Install the process-wide rustls CryptoProvider (ring), idempotently.
rustls 0.23 builds no TLS config until a provider is selected. It can
auto-pick one from crate features, but only when exactly one of rustls’
ring/aws-lc-rs features is enabled in the final binary’s dependency
closure. huddle-core pulls rustls via tokio-tungstenite’s wss:// door
without a provider feature, so before this fix only the TUI worked (it
enables ring transitively through ureq); huddle-gui’s wss worker
thread panicked at startup. We now depend on rustls’ ring directly and
install it here, so every consumer is deterministic regardless of which
other crates happen to be in the closure.
Called at the top of the AppHandle start path,
before any transport door builds a TLS config. Safe to call repeatedly —
a second call (or one racing a transitive dep’s install) is a no-op.
