Enum TlsConfigError 

#[non_exhaustive]
pub enum TlsConfigError {
    NoCryptoProvider,
    FipsHardeningFailed(String),
    Other(Box<dyn Error + Send + Sync + 'static>),
}

Error type returned by the fallible TLS-config builders in this gear.

The Other variant carries a boxed dyn Error so the source-error chain from rustls (and any future foreign error) is preserved end-to-end — downstream HttpError::Tls(_) wraps this and reports a proper .source().

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

NoCryptoProvider

rustls::crypto::CryptoProvider::get_default() returned None when a FIPS-mode TLS config was requested. Under --features fips the crypto provider must be installed up-front via toolkit::bootstrap::init_crypto_provider; falling back to an uninstalled provider here would silently bypass the canonical install path and yield a config whose FIPS-validation status is indeterminate.

FipsHardeningFailed(String)

apply_fips_hardening rejected the freshly-built ClientConfig because ClientConfig::fips() reported false. Carries the human-readable diagnostic. Under normal bootstrap flow the provider-level witness is already asserted by init_crypto_provider; this error surfaces per-config issues (e.g. missing require_ems) or a missed init_crypto_provider() call.

Other(Box<dyn Error + Send + Sync + 'static>)

Catch-all for foreign errors (rustls::Error, etc.) propagated via ?. Marked #[error(transparent)] so the Display and source() impls forward to the inner error unchanged.

Trait Implementations

impl Debug for TlsConfigError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for TlsConfigError

fn fmt(&self, __formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for TlsConfigError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl From<Box<dyn Error + Send + Sync>> for TlsConfigError

fn from(source: Box<dyn Error + Send + Sync + 'static>) -> Self

Converts to this type from the input type.
