Enum packed_struct::EnumCatchAll

pub enum EnumCatchAll<E> where
    E: PrimitiveEnum,  {
    Enum(E),
    CatchAll(E::Primitive),
}

A wrapper for primitive enums that supports catching and retaining any values that don't have defined discriminants.

Variants

Enum(E)

A matched discriminant

CatchAll(E::Primitive)

Some other value, stored as the primitive type

Implementations

impl<E> EnumCatchAll<E> where
    E: PrimitiveEnum, 

pub fn from_enum(v: E) -> Self

Trait Implementations

impl<E: Clone> Clone for EnumCatchAll<E> where
    E: PrimitiveEnum,
    E::Primitive: Clone, 

fn clone(&self) -> EnumCatchAll<E>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<E: Copy> Copy for EnumCatchAll<E> where
    E: PrimitiveEnum,
    E::Primitive: Copy, 

impl<E: Debug> Debug for EnumCatchAll<E> where
    E: PrimitiveEnum,
    E::Primitive: Debug, 

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

Formats the value using the given formatter.

impl<E> From<E> for EnumCatchAll<E> where
    E: PrimitiveEnum, 

fn from(v: E) -> Self

Performs the conversion.

impl<E> PartialEq<EnumCatchAll<E>> for EnumCatchAll<E> where
    E: PrimitiveEnum, 

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

This method tests for self and other values to be equal, and is used by ==.

#[must_use]fn ne(&self, other: &Rhs) -> bool

This method tests for !=.

impl<E> PrimitiveEnum for EnumCatchAll<E> where
    E: PrimitiveEnum, 

type Primitive = E::Primitive

The primitve type into which we serialize and deserialize ourselves.

fn from_primitive(val: E::Primitive) -> Option<Self>

Convert from a primitive, might fail.

fn to_primitive(&self) -> E::Primitive

Convert to a primitive value.

fn from_str(s: &str) -> Option<Self>

Convert from a string value representing the variant. Case sensitive.

fn from_str_lower(s: &str) -> Option<Self>

Convert from a string value representing the variant. Lowercase.

impl<E> PrimitiveEnumDynamicStr for EnumCatchAll<E> where
    E: PrimitiveEnum + PrimitiveEnumDynamicStr, 

fn to_display_str(&self) -> Cow<'static, str>

Display value, same as the name of a particular variant.

fn all_variants() -> Cow<'static, [Self]>

A list all possible string variants.
