Struct arithmetic_parser::Destructure

pub struct Destructure<'a, T> {
    pub start: Vec<SpannedLvalue<'a, T>>,
    pub middle: Option<Spanned<'a, DestructureRest<'a, T>>>,
    pub end: Vec<SpannedLvalue<'a, T>>,
}

Tuple destructuring, such as (a, b, ..., c).

Fields

start: Vec<SpannedLvalue<'a, T>>

Start part of the destructuring, e.g, a and b in (a, b, ..., c).

middle: Option<Spanned<'a, DestructureRest<'a, T>>>

Middle part of the destructuring, e.g., rest in (a, b, ...rest, _).

end: Vec<SpannedLvalue<'a, T>>

End part of the destructuring, e.g., c in (a, b, ..., c).

Implementations

impl<T> Destructure<'_, T>

pub fn len(&self) -> LvalueLen

Returns the length of destructured elements.

pub fn is_empty(&self) -> bool

Checks if the destructuring is empty.

Trait Implementations

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

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

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

Formats the value using the given formatter.

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

fn eq(&self, other: &Destructure<'a, 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.
