Enum TraitItem

#[non_exhaustive]
pub enum TraitItem {
    Const(TraitItemConst),
    Fn(TraitItemFn),
    Type(TraitItemType),
    Macro(TraitItemMacro),
    Verbatim(TokenStream),
}

Available on crate feature full only.

An item declaration within the definition of a trait.

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

fn clone(&self) -> Self

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TraitItem

Available on crate feature extra-traits only.

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

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

Converts to this type from the input type.

impl Hash for TraitItem

Available on crate feature extra-traits only.

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

where H: Hasher,

Feeds this value into the given Hasher.

impl Parse for TraitItem

Available on crate feature parsing only.

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

impl PartialEq for TraitItem

Available on crate feature extra-traits only.

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

Write self to the given TokenStream.

fn to_token_stream(&self) -> TokenStream

Convert self directly into a TokenStream object.

where Self: Sized,

Convert self directly into a TokenStream object.

impl Eq for TraitItem

Available on crate feature extra-traits only.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
