Available on crate feature tls only.

Why TLS did not start.

No variant carries key material, and two of them deliberately carry no source either: a PEM parse error’s one useful field is the input it choked on, and for key that input is the private key. A path, the configuration key that names it, and what to do about it is the whole budget.

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.

Unreadable

A configured file could not be opened or read.

Fields

path: PathBuf

The file.

key: &'static str

The configuration key that named it.

source: Error

The I/O error. Never a parse error — see the type’s note.

PermissiveKey

A private key’s permissions let somebody other than its owner read it.

Fields

path: PathBuf

The file.

mode: u32

Its mode, masked to the permission bits.

UnusablePem

A file that should hold PEM does not.

Fields

path: PathBuf

The file.

key: &'static str

The configuration key that named it.

UnusableKey

The key file holds no private key this build can use.

Fields

path: PathBuf

The file.

NoCertificates

A PEM file that should hold certificates holds none.

Fields

path: PathBuf

The file.

key: &'static str

The configuration key that named it.

UnusableClientCa

client_ca holds nothing that can act as a trust anchor.

Fields

path: PathBuf

The file.

source: Error

What rustls made of it. A certificate is public, so this one may carry its source.

KeyDoesNotMatch

The private key is not the certificate’s key, or is of a type this build cannot sign with.

Fields

certificate: PathBuf

The certificate.

key: PathBuf

The key.

Provider

The cryptography provider would not accept the default protocol versions, which is a build problem rather than a configuration one.

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, f: &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.
