Errors that can occur during TLS operations.

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.

HandshakeFailed(String)

TLS handshake failed.

CertificateValidation(String)

Certificate validation failed.

HostnameVerification

Hostname verification failed.

Fields

expected: String

Expected hostname.

actual: String

Actual hostname from certificate.

InvalidCertificate(String)

Invalid certificate format.

InvalidPrivateKey(String)

Invalid private key format.

Configuration(String)

TLS configuration error.

Io(Error)

IO error during TLS operations.

Rustls(Error)

Rustls error.

EncryptionRequired

Server requires encryption but client disabled it.

EncryptionNotSupported

Client requires encryption but server doesn’t support it.

StrictModeRequired

TDS 8.0 strict mode is required but not supported.

ConnectionClosed

Connection closed during TLS negotiation.

Implementations

impl TlsError

pub fn is_transient(&self) -> bool

Check if this error is transient and may succeed on retry.

IO errors and connection closures are transient. Certificate and configuration errors are terminal.

pub fn is_terminal(&self) -> bool

Check if this error is terminal and will never succeed on retry.

Certificate validation failures, configuration errors, and encryption mode mismatches are permanent.

Trait Implementations

impl Debug for TlsError

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

Formats the value using the given formatter.

impl Display for TlsError

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

Formats the value using the given formatter.

impl Error for TlsError

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<Error> for TlsError

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<Error> for TlsError

fn from(source: Error) -> Self
