Trait Implementations

impl Clone for Question

fn clone(&self) -> Question

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Question

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

Formats the value using the given formatter.

impl Default for Question

fn default() -> Question

Returns the “default value” for a type.

impl Deref for Question

type Target = WithSpan

The resulting type after dereferencing.

fn deref(&self) -> &<Question as Deref>::Target

Dereferences the value.

impl DerefMut for Question

fn deref_mut(&mut self) -> &mut <Question as Deref>::Target

Mutably dereferences the value.

impl Hash for Question

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 Question

fn parse(input: &ParseBuffer<'_>) -> Result<Question, Error>

impl PartialEq for Question

fn eq(&self, _other: &Question) -> 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.

impl ToTokens for Question

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) -> TokenStream

where Self: Sized,

Convert self directly into a TokenStream object.

impl Copy for Question

impl Eq for Question

impl Token for Question
