Enum TransportOptionRegistryError 

#[non_exhaustive]
pub enum TransportOptionRegistryError {
    DuplicateProviderKey {
        provider_key: &'static str,
        existing_type: &'static str,
        new_type: &'static str,
    },
}

Failure to register a provider-option codec.

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.

DuplicateProviderKey

Two different option types claimed the same stable provider key.

Fields

provider_key: &'static str

Provider key claimed by both option types.

existing_type: &'static str

Fully qualified name of the previously registered type.

new_type: &'static str

Fully qualified name of the type that attempted registration.

Trait Implementations

impl Debug for TransportOptionRegistryError

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

Formats the value using the given formatter.

impl Display for TransportOptionRegistryError

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

impl Error for TransportOptionRegistryError

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>)
