Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for DeriveInput

Available on crate feature extra-traits only.

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

Formats the value using the given formatter.

impl From<DeriveInput> for Item

fn from(input: DeriveInput) -> Item

Converts to this type from the input type.

impl From<ItemEnum> for DeriveInput

fn from(input: ItemEnum) -> DeriveInput

Converts to this type from the input type.

impl From<ItemStruct> for DeriveInput

fn from(input: ItemStruct) -> DeriveInput

Converts to this type from the input type.

impl From<ItemUnion> for DeriveInput

fn from(input: ItemUnion) -> DeriveInput

Converts to this type from the input type.

impl Hash for DeriveInput

Available on crate feature extra-traits only.

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 DeriveInput

Available on crate feature parsing only.

fn parse(input: ParseStream<'_>) -> Result<Self>

impl PartialEq<DeriveInput> for DeriveInput

Available on crate feature extra-traits only.

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