Enum Item

#[non_exhaustive]
pub enum Item {
    Use(ItemUse),
    Fn(ItemFn),
    Enum(ItemEnum),
    Struct(ItemStruct),
    Impl(ItemImpl),
    Mod(ItemMod),
    Const(ItemConst),
    MacroCall(MacroCall),
}

A declaration.

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.

Use(ItemUse)

A use declaration.

Fn(ItemFn)

A function declaration.

Enum(ItemEnum)

An enum declaration.

Struct(ItemStruct)

A struct declaration.

Impl(ItemImpl)

An impl declaration.

Mod(ItemMod)

A module declaration.

Const(ItemConst)

A const declaration.

MacroCall(MacroCall)

A macro call expanding into an item.

Trait Implementations

impl Debug for Item

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

Formats the value using the given formatter.

impl OptionSpanned for Item

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

Get the optional span of the type.

impl Parse for Item

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

Parse the current item from the parser.

impl PartialEq for Item

fn eq(&self, other: &Item) -> 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 Item

fn span(&self) -> Span

Get the span of the type.

impl ToTokens for Item

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

Turn the current item into tokens.

impl TryClone for Item

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 Item

impl StructuralPartialEq for Item
