Struct RustlsClientConfig 

pub struct RustlsClientConfig(/* private fields */);

Available on crate feature client only.

Rustls ClientConfig wrapper used by RustlsConfig.

RustlsClientConfig::default trusts the platform or webpki roots (depending on the platform-verifier feature). Use RustlsClientConfig::from_root_cert_pem to trust a specific private or self-signed certificate instead, or convert an existing ClientConfig via From.

Implementations

impl RustlsClientConfig

pub fn from_root_cert_pem(pem: &[u8]) -> Result<Self>

Build a client configuration that trusts exactly the certificate(s) in pem.

Unlike RustlsClientConfig::default, this consults neither the platform trust store nor the webpki root bundle — the provided roots are the only trust anchors. Server authentication is otherwise unchanged: certificate chains, signatures, expiry, and server name are all still verified against these roots. This is the right tool for talking to a service that presents a private or self-signed certificate.

The crate’s configured crypto provider and default ALPN protocol list (h2, http/1.1) are reused.

Errors

Returns an error if pem contains no certificates or cannot be parsed, or if the resulting trust anchors are rejected by the verifier builder.

impl RustlsClientConfig

pub fn dangerously_accept_any_cert() -> Self

Available on crate feature dangerous only.

Build a client configuration that accepts any server certificate without verification.

⚠️ This disables server authentication entirely: handshake signatures are still checked, but the certificate is never validated against any trust anchor, so the connection is vulnerable to man-in-the-middle attacks. It exists for development against throwaway self-signed certificates and for --insecure-style CLI flags. For talking to a service with a known private certificate, prefer RustlsClientConfig::from_root_cert_pem, which keeps authentication intact.

This constructor is only available with the dangerous crate feature enabled, and logs a warning when called.
