Enum TlsError 

#[non_exhaustive]
pub enum TlsError {
    UnusableName(String),
    Material {
        what: String,
        detail: String,
    },
    Config(String),
    Handshake {
        peer: String,
        detail: String,
    },
}

What can go wrong establishing TLS.

The variants are separate because expired, wrong-host and unknown-issuer are three different operational problems with three different fixes. Collapsing them into “handshake failed” costs an engineer an afternoon.

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.

UnusableName(String)

The name to verify against is not a valid DNS name.

Material

A certificate or key could not be read.

Fields

what: String

Which file or blob.

detail: String

What was wrong with it.

Config(String)

The configuration itself is invalid.

Handshake

The handshake failed — including every verification failure, which rustls reports as an alert with its reason attached.

Fields

peer: String

Who we were talking to.

detail: String

What went wrong, as reported by the TLS library.

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<TlsError> for Error

fn from(source: TlsError) -> Self

Converts to this type from the input type.
