Enum SettingError 

#[non_exhaustive]
pub enum SettingError {
    InvalidKey(String),
    Duplicate(String),
    EmptyLabel,
    InvalidChoice,
    EmptyRange,
    InvalidStep,
    DefaultOutOfRange,

}

Why a setting was refused at registration.

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.

InvalidKey(String)

The key is empty, too long, starts with . or holds another character than a-z, 0-9, _, - and ..

Duplicate(String)

The mod registered a setting with this key already.

EmptyLabel

The label (or an option of a choice) is empty.

InvalidChoice

A choice has no options, or its default is not one of them.

EmptyRange

A range’s min is not below its max, or a bound is not finite.

InvalidStep

A range’s step is zero, negative, not finite or wider than the range.

DefaultOutOfRange

A range’s default is outside min..=max.

ColorAlpha

A colour holds alpha or more than 24 bits.

Trait Implementations

impl Clone for SettingError

fn clone(&self) -> SettingError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SettingError

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

impl Eq for SettingError

impl Error for SettingError

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 SettingError

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

Equality operator ==.

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

Inequality operator !=.

impl StructuralPartialEq for SettingError

impl Wire for SettingError

const MIN: usize = 4usize

Minimum encoded size, used to reject impossible collection lengths.

fn put(&self, out: &mut Writer)

Encodes this value, recording failures on the writer.

fn put_owned(self, out: &mut Writer)

Consumes owned data when a resource’s ownership must cross the boundary.

fn take(input: &mut Reader<'_>) -> Result<SettingError, WireError>

Decodes one value, leaving any following bytes for the caller.
