Struct ItemEnum

#[non_exhaustive]
pub struct ItemEnum {
    pub attributes: Vec<Attribute>,
    pub visibility: Visibility,
    pub enum_token: Enum,
    pub name: Ident,
    pub variants: Braced<ItemVariant, Comma>,
}

An enum item.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

attributes: Vec<Attribute>

The attributes for the enum block

visibility: Visibility

The visibility of the enum item

enum_token: Enum

The enum token.

name: Ident

The name of the enum.

variants: Braced<ItemVariant, Comma>

Variants in the enum.

Implementations

impl ItemEnum

pub fn parse_with_meta( parser: &mut Parser<'_>, attributes: Vec<Attribute>, visibility: Visibility, ) -> Result<Self, Error>

Parse #ident and attach the given meta

Trait Implementations

impl Debug for ItemEnum

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

Formats the value using the given formatter.

impl OptionSpanned for ItemEnum

fn option_span(&self) -> Option<Span>

Get the optional span of the type.

impl Parse for ItemEnum

fn parse(p: &mut Parser<'_>) -> Result<Self>

Parse the current item from the parser.

impl PartialEq for ItemEnum

fn eq(&self, other: &ItemEnum) -> 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 Spanned for ItemEnum

fn span(&self) -> Span

Get the span of the type.

impl ToTokens for ItemEnum

fn to_tokens( &self, context: &mut MacroContext<'_, '_, '_>, stream: &mut TokenStream, ) -> Result<()>

Turn the current item into tokens.

impl TryClone for ItemEnum

fn try_clone(&self) -> Result<Self>

Try to clone the current value, raising an allocation error if it’s unsuccessful.

fn try_clone_from(&mut self, source: &Self) -> Result<(), Error>

Performs copy-assignment from source.

impl Eq for ItemEnum
