Struct RustlsProvider 

#[non_exhaustive]
pub struct RustlsProvider {
    config: Arc<ClientConfig>,
}

A TlsProvider that uses rustls.

It supports wrapping any reasonable stream type that implements AsyncRead + AsyncWrite.

Cryptographic providers

The application is responsible for calling CryptoProvider::install_default() before constructing TlsProvider. If they do not, rustls will fail, and arti will not run.

We currently recommend the aws-lc-rs provider because, of the two builtin providers that ship with rustls, it appears to have better performance, and it supports hybrid post-quantum handshakes. It used to have a problematic license, but this has been fixed since March 2026.

See the rustls documentation for a list of other rustls cryptography providers.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

config: Arc<ClientConfig>

Inner ClientConfig logic used to create connectors.
