Enum NotAvailable

pub enum NotAvailable {
    NotImplemented,
    NotSupported,
}

🚩+ An error composite of NotImplemented + NotSupported.

Used in methods of:

• DataCollection.

Variants

NotImplemented

The requested functionality is not implemented.

NotSupported

Implementations

impl NotAvailable

pub const fn from_not_implemented(_f: NotImplemented) -> NotAvailable

const version of From<NotImplemented> for NotAvailable.

impl NotAvailable

pub const fn from_not_supported(_f: NotSupported) -> NotAvailable

const version of From<NotSupported> for NotAvailable.

Trait Implementations

impl Clone for NotAvailable

fn clone(&self) -> NotAvailable

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for NotAvailable

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

Formats the value using the given formatter.

impl Display for NotAvailable

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

Formats the value using the given formatter.

impl Error for NotAvailable

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 ExtError for NotAvailable

type Kind = ()

Represents the specific kind of error, if applicable.

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

Checks if two errors are equivalent based on their kind or other criteria.

fn error_kind(&self) -> Self::Kind

Returns the kind of the error, if applicable.

impl From<NotAvailable> for DataError

Available on crate feature error and data·· only.

fn from(f: NotAvailable) -> DataError

Converts to this type from the input type.

impl From<NotImplemented> for NotAvailable

fn from(_f: NotImplemented) -> NotAvailable

Converts to this type from the input type.

impl From<NotSupported> for NotAvailable

fn from(_f: NotSupported) -> NotAvailable

Converts to this type from the input type.

impl Hash for NotAvailable

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for NotAvailable

fn eq(&self, other: &NotAvailable) -> 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.

impl TryFrom<DataError> for NotAvailable

Available on crate feature error and data·· only.

type Error = FailedErrorConversion

The type returned in the event of a conversion error.

fn try_from(f: DataError) -> Result<NotAvailable, FailedErrorConversion>

Performs the conversion.

impl TryFrom<NotAvailable> for NotImplemented

type Error = FailedErrorConversion

The type returned in the event of a conversion error.

fn try_from(_f: NotAvailable) -> Result<NotImplemented, Self::Error>

Performs the conversion.

impl TryFrom<NotAvailable> for NotSupported

type Error = FailedErrorConversion

The type returned in the event of a conversion error.

fn try_from(_f: NotAvailable) -> Result<NotSupported, Self::Error>

Performs the conversion.
