Enum TypeClassError 

#[non_exhaustive]
pub enum TypeClassError {
    Empty,
    InvalidChar {
        char: char,
        position: usize,
    },
}

Errors for type-class parsing.

Produced by ExtensionClass::new and by TypeClass’s FromStr implementation, which reaches an extension class for anything outside the core set.

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.

Empty

The class name is empty.

InvalidChar

The name contains something other than a lowercase ASCII letter.

Fields

char: char

The invalid character

position: usize

Position in the input, in characters

Trait Implementations

impl Clone for TypeClassError

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for TypeClassError

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

Formats the value using the given formatter.

impl Display for TypeClassError

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

Formats the value using the given formatter.

impl Eq for TypeClassError

impl Error for TypeClassError

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 TypeClassError

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

Equality operator ==.

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

Inequality operator !=.
