Enum CryptoProviderError 

pub enum CryptoProviderError {
    AlreadyInstalled,
}

Errors raised when installing the rustls crypto provider.

Separate from crate::error::WebSocketError because this is a one-shot startup concern distinct from runtime protocol errors; folding it into WebSocketError would bloat the main enum for a call that runs once per process.

Variants

AlreadyInstalled

A rustls crypto provider is already installed in this process.

rustls stores its crypto provider in a process-global OnceCell-style slot; subsequent install_default calls are rejected. This variant carries no payload because the already- installed provider is rarely actionable from the caller, and exposing an Arc<CryptoProvider> here would leak a rustls type into callers that are compiled under native-tls.

Trait Implementations

impl Debug for CryptoProviderError

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

Formats the value using the given formatter.

impl Display for CryptoProviderError

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

Formats the value using the given formatter.

impl Error for CryptoProviderError

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>)
