Struct Return 

pub struct Return {
    pub span: Span,
    pub value: Option<Expr>,
}

A return expression.

Fields

span: Span

value: Option<Expr>

Implementations

impl Return

pub fn parse( cx: &mut Context, tokens: &mut TokenIter<'_, '_>, ) -> Result<Self, Recoverable>

Parses a Return statement from the provided stream.

Trait Implementations

impl Clone for Return

fn clone(&self) -> Return

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Return

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

Formats the value using the given formatter.

impl Ord for Return

fn cmp(&self, other: &Return) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Return

fn eq(&self, other: &Return) -> 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 PartialOrd for Return

fn partial_cmp(&self, other: &Return) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Spanned for Return

fn span(&self) -> Span

Returns the Span of this object.

impl Eq for Return
