Implementations

where T: Builtin + 'static,

pub fn new_primitive_call<T>(x: T, args: ExprList) -> Self

where T: Builtin + 'static,

Trait Implementations

impl Clone for Expr

fn clone(&self) -> Expr

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Expr

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

Formats the value using the given formatter.

impl Display for Expr

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

Formats the value using the given formatter.

impl From<Expr> for ExprList

fn from(value: Expr) -> Self

Converts to this type from the input type.

impl FromIterator<Expr> for ExprList

fn from_iter<T>(iter: T) -> Self

where T: IntoIterator<Item = Expr>,

Creates a value from an iterator.

impl PartialEq for Expr

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