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.

Const(TraitItemConst)

An associated constant within the definition of a trait.

Fn(TraitItemFn)

An associated function within the definition of a trait.

Type(TraitItemType)

An associated type within the definition of a trait.

Macro(TraitItemMacro)

A macro invocation within the definition of a trait.

Verbatim(TokenStream)

Tokens within the definition of a trait not interpreted by Syn.

Trait Implementations

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TraitItem

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

Formats the value using the given formatter.

impl From<TraitItemConst> for TraitItem

fn from(e: TraitItemConst) -> TraitItem

Converts to this type from the input type.

impl From<TraitItemFn> for TraitItem

fn from(e: TraitItemFn) -> TraitItem

Converts to this type from the input type.

impl From<TraitItemMacro> for TraitItem

fn from(e: TraitItemMacro) -> TraitItem

Converts to this type from the input type.

impl From<TraitItemType> for TraitItem

fn from(e: TraitItemType) -> TraitItem

impl Hash for TraitItem

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,

impl Parse for TraitItem

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

impl PartialEq for TraitItem

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

fn to_token_stream(&self) -> TokenStream

Convert self directly into a TokenStream object.

fn into_token_stream(self) -> TokenStream

where Self: Sized,
