Enum RegistryError 

pub enum RegistryError {
    DuplicateId(String),
    DuplicateExtension {
        extension: String,
        existing: String,
        incoming: String,
    },
    InvalidExtension {
        language: String,
        extension: String,
        reason: &'static str,
    },
}

Why a language could not be registered.

impl Eq for RegistryError

impl Error for RegistryError

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 PartialEq for RegistryError

fn eq(&self, other: &RegistryError) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
