Enum arithmetic_parser::DestructureRest

pub enum DestructureRest<'a, T> {
    Unnamed,
    Named {
        variable: Span<'a>,
        ty: Option<Spanned<'a, T>>,
    },
}

Rest syntax, such as ...rest in (a, ...rest, b).

Variants

Unnamed

Unnamed rest syntax, i.e., ....

Named

Named rest syntax, e.g., ...rest.

Fields of Named

variable: Span<'a>

Variable span, e.g., rest.

ty: Option<Spanned<'a, T>>

Type annotation of the value.

Implementations

impl<'a, T> DestructureRest<'a, T>

pub fn to_lvalue(&self) -> Option<SpannedLvalue<'a, T>>

Tries to convert this rest declaration into an lvalue. Return None if the rest declaration is unnamed.

Trait Implementations

impl<'a, T: Clone> Clone for DestructureRest<'a, T>

fn clone(&self) -> DestructureRest<'a, T>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a, T: Debug> Debug for DestructureRest<'a, T>

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

Formats the value using the given formatter.

impl<'a, T: PartialEq> PartialEq<DestructureRest<'a, T>> for DestructureRest<'a, T>

fn eq(&self, other: &DestructureRest<'a, T>) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &DestructureRest<'a, T>) -> bool

This method tests for !=.
