Enum devise::syn::ForeignItem

pub enum ForeignItem {
    Fn(ForeignItemFn),
    Static(ForeignItemStatic),
    Type(ForeignItemType),
    Macro(ForeignItemMacro),
    Verbatim(TokenStream),
}

An item within an extern block.

Syntax tree enum

This type is a syntax tree enum.

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.

Fn(ForeignItemFn)

A foreign function in an extern block.

Static(ForeignItemStatic)

A foreign static item in an extern block: static ext: u8.

Type(ForeignItemType)

A foreign type in an extern block: type void.

Macro(ForeignItemMacro)

A macro invocation within an extern block.

Verbatim(TokenStream)

Tokens in an extern block not interpreted by Syn.

Trait Implementations

impl Clone for ForeignItem

fn clone(&self) -> ForeignItem

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ForeignItem

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

Formats the value using the given formatter.

impl From<ForeignItemFn> for ForeignItem

fn from(e: ForeignItemFn) -> ForeignItem

Converts to this type from the input type.

impl From<ForeignItemMacro> for ForeignItem

fn from(e: ForeignItemMacro) -> ForeignItem

Converts to this type from the input type.

impl From<ForeignItemStatic> for ForeignItem

fn from(e: ForeignItemStatic) -> ForeignItem

Converts to this type from the input type.

impl From<ForeignItemType> for ForeignItem

fn from(e: ForeignItemType) -> ForeignItem

Converts to this type from the input type.

impl Hash for ForeignItem

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

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 Parse for ForeignItem

fn parse(input: &ParseBuffer<'_>) -> Result<ForeignItem, Error>

impl PartialEq<ForeignItem> for ForeignItem

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

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

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

fn to_tokens(&self, tokens: &mut TokenStream)

Write self to the given TokenStream.

fn to_token_stream(&self) -> TokenStream

Convert self directly into a TokenStream object.

fn into_token_stream(self) -> TokenStreamwhere Self: Sized,

Convert self directly into a TokenStream object.
