Enum InvalidClassName 

pub enum InvalidClassName {
    Empty {
        name: Cow<'static, str>,
    },
    ContainsWhitespace {
        name: Cow<'static, str>,
    },
}

Possible reasons why a candidate name is not a valid class name.

Variants

Empty

The name was empty or contained only whitespace (any Unicode whitespace character, including ASCII space/tab/newline and characters such as the non-breaking space U+00A0).

Fields

name: Cow<'static, str>

The offending input (itself blank).

ContainsWhitespace

The name contained whitespace, suggesting the caller passed a whitespace-separated class list rather than a single token. “Whitespace” here is the Unicode definition (char::is_whitespace), which covers ASCII space/tab/newline and characters such as the non-breaking space U+00A0 that paste-from-rich-text sources sometimes inject.

Fields

name: Cow<'static, str>

The offending input.

Trait Implementations

impl Clone for InvalidClassName

fn clone(&self) -> InvalidClassName

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for InvalidClassName

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

Formats the value using the given formatter.

impl Display for InvalidClassName

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

Formats the value using the given formatter.

impl Error for InvalidClassName

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 InvalidClassName

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
