Enum syn::NestedMeta

pub enum NestedMeta {
    Meta(Meta),
    Lit(Lit),
}

Element of a compile-time attribute list.

This type is available only if Syn is built with the "derive" or "full" feature.

Variants

Meta(Meta)

A structured meta item, like the Copy in #[derive(Copy)] which would be a nested Meta::Path.

Lit(Lit)

A Rust literal, like the "new_name" in #[rename("new_name")].

Trait Implementations

impl Clone for NestedMeta

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 NestedMeta

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

Formats the value using the given formatter.

impl From<Lit> for NestedMeta

fn from(e: Lit) -> NestedMeta

Converts to this type from the input type.

impl From<Meta> for NestedMeta

fn from(e: Meta) -> NestedMeta

Converts to this type from the input type.

impl Hash for NestedMeta

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 NestedMeta

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

impl PartialEq<NestedMeta> for NestedMeta

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.

impl ToTokens for NestedMeta

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.
