Enum syn::ImplItem

#[non_exhaustive]
pub enum ImplItem {
    Const(ImplItemConst),
    Method(ImplItemMethod),
    Type(ImplItemType),
    Macro(ImplItemMacro),
    Verbatim(TokenStream),
}

Available on crate feature full only.

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.

Const(ImplItemConst)

An associated constant within an impl block.

Method(ImplItemMethod)

A method within an impl block.

Type(ImplItemType)

An associated type within an impl block.

Macro(ImplItemMacro)

A macro invocation within an impl block.

Verbatim(TokenStream)

Tokens within an impl block not interpreted by Syn.

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ImplItem

Available on crate feature extra-traits only.

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

Formats the value using the given formatter.

fn from(e: ImplItemConst) -> ImplItem

Converts to this type from the input type.

impl From<ImplItemMacro> for ImplItem

fn from(e: ImplItemMacro) -> ImplItem

Converts to this type from the input type.

impl From<ImplItemMethod> for ImplItem

fn from(e: ImplItemMethod) -> ImplItem

Converts to this type from the input type.

impl From<ImplItemType> for ImplItem

fn from(e: ImplItemType) -> ImplItem

impl Hash for ImplItem

Available on crate feature extra-traits only.

Available on crate feature parsing only.

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

impl PartialEq<ImplItem> for ImplItem

Available on crate feature extra-traits only.

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