Struct proc_macro_kwargs::parse::Syn

pub struct Syn<T: Parse>(pub T);

Wrapper type that parses via syn’s Parse trait

Through this wrapper, any AST node can be parsed as a MacroArg

Tuple Fields

0: T

Implementations

impl<T: Parse> Syn<T>

pub fn into_inner(self) -> T

Convert this type into its inner type

Trait Implementations

impl<T: Clone + Parse> Clone for Syn<T>

fn clone(&self) -> Syn<T>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T: Debug + Parse> Debug for Syn<T>

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

Formats the value using the given formatter.

impl<T: Parse> Deref for Syn<T>

type Target = T

The resulting type after dereferencing.

fn deref(&self) -> &T

Dereferences the value.

impl<T: Parse> DerefMut for Syn<T>

fn deref_mut(&mut self) -> &mut T

Mutably dereferences the value.

impl<T: Parse> From<T> for Syn<T>

fn from(t: T) -> Syn<T>

Converts to this type from the input type.

impl<T: Hash + Parse> Hash for Syn<T>

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

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<T> MacroArg for Syn<T>

where T: Parse,

fn parse_macro_arg(stream: ParseStream<'_>) -> Result<Self>

Parse the argument to the macro

impl<T: Parse> Parse for Syn<T>

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

impl<T: PartialEq + Parse> PartialEq for Syn<T>

fn eq(&self, other: &Syn<T>) -> 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<T: Parse + ToTokens> ToTokens for Syn<T>

fn to_tokens(&self, stream: &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) -> TokenStream

Convert self directly into a TokenStream object.

impl<T: Copy + Parse> Copy for Syn<T>

impl<T: Eq + Parse> Eq for Syn<T>

impl<T: Parse> StructuralPartialEq for Syn<T>
