Struct DisabledVariant

pub struct DisabledVariant;

Error type for all enum conversions of the form impl TryFrom<AllFoo> for Foo.

The error is returned for variants from the full enum that are disabled in the main enum because of the compile-time configuration. For example:

use std::convert::TryInto;
let val: Result<PartOfSpeech, _> = AllPartOfSpeech::NariAdjective.try_into();
#[cfg(feature = "scope-archaic")]
assert_eq!(val, Ok(PartOfSpeech::NariAdjective));
#[cfg(not(feature = "scope-archaic"))]
assert_eq!(val, Err(DisabledVariant));

Trait Implementations

impl Clone for DisabledVariant

fn clone(&self) -> DisabledVariant

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DisabledVariant

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

Formats the value using the given formatter.

impl Default for DisabledVariant

fn default() -> DisabledVariant

Returns the “default value” for a type.

impl Hash for DisabledVariant

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 DisabledVariant

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