pub const fn new(lhs: E, rhs: E) -> Self

Trait Implementations

impl<E: Clone> Clone for First<E>

fn clone(&self) -> First<E>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<E: Debug> Debug for First<E>

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

Formats the value using the given formatter.

impl<V, S, O> From<(Spanned<Node<V, S, O>, S>, Spanned<Node<V, S, O>, S>)> for First<AST<V, S, O>>

fn from(e: (AST<V, S, O>, AST<V, S, O>)) -> Self

Converts to this type from the input type.

impl<E> From<First<E>> for Choice<E>

fn from(first: First<E>) -> Self

Converts to this type from the input type.

impl<E: PartialEq> PartialEq for First<E>

fn eq(&self, other: &First<E>) -> 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.
