pub struct Returns {
    pub returns_token: returns,
    pub paren_token: Paren,
    pub returns: ParameterList,
}

The returns attribute of a function.

Fields

returns_token: returns

paren_token: Paren

returns: ParameterList

The returns of the function. This cannot be parsed empty.

Implementations

impl Returns

pub fn new(span: Span, returns: ParameterList) -> Self

pub fn parse_opt(input: ParseStream<'_>) -> Result<Option<Self>>

Trait Implementations

impl Clone for Returns

fn clone(&self) -> Returns

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Returns

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

Formats the value using the given formatter.

impl Display for Returns

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

Formats the value using the given formatter.

impl Eq for Returns

impl Hash for Returns

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 Parse for Returns

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

impl PartialEq for Returns

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

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.

impl Spanned for Returns

fn span(&self) -> Span

Returns a Span covering the complete contents of this syntax tree node, or Span::call_site() if this node is empty.

fn set_span(&mut self, span: Span)

Sets the span of this syntax tree node if it is not empty.

fn with_span(self, span: Span) -> Self

where Self: Sized,

Sets the span of this owned syntax tree node if it is not empty.

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.
