Enum SecureConnectError 

#[non_exhaustive]
pub enum SecureConnectError {
    TlsConfiguration(TlsConfigurationError),
    DriverTlsConfiguration {
        band: u8,
    },
    Runtime(RuntimeError),
}

Error returned by typed secure connection and lifecycle entry points.

This additive type keeps TLS configuration failures matchable without adding a variant to the released, exhaustively matchable RuntimeError.

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.

TlsConfiguration(TlsConfigurationError)

Custom or native trust material failed validation before network I/O.

DriverTlsConfiguration

A driver band could not lower the already validated TLS policy.

Fields

band: u8

Driver protocol band that rejected the configuration.

Runtime(RuntimeError)

The connection reached the ordinary version gate or driver runtime.

Implementations

impl SecureConnectError

pub fn configuration_code(&self) -> Option<&'static str>

Return the stable TLS configuration code, or None for an ordinary version/connection/runtime failure.

pub fn credential_safe_diagnostic(&self) -> Option<String>

Return a diagnostic that is safe to expose after credentials have been resolved.

TLS diagnostics are reconstructed from typed codes without retaining configured paths. Version diagnostics are retained only for variants whose fields are closed version/band data. Probe, parse, connection, query, and transaction failures may contain provider-controlled text and therefore return None.

pub fn into_runtime_error(self) -> RuntimeError

Collapse an additive secure error onto the released runtime surface.

Trait Implementations

impl Debug for SecureConnectError

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

Formats the value using the given formatter.

impl Display for SecureConnectError

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

Formats the value using the given formatter.

impl Error for SecureConnectError

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<RuntimeError> for SecureConnectError

fn from(source: RuntimeError) -> Self

Converts to this type from the input type.

impl From<TlsConfigurationError> for SecureConnectError

fn from(source: TlsConfigurationError) -> Self

Converts to this type from the input type.
