Struct r::callable::primitive::PrimitiveSubstitute

pub struct PrimitiveSubstitute;

Substitute Expressions

Under construction! There are known differences with R’s subsitute(). Notably, atomic values will not yet be substituted.

In-Language

Usage

substitute(expr, envir = environment())

Arguments

expr: Quoted code to evaluate. envir: An environment in which to substitute the expression, defaulting to the current environment.

Examples

x <- quote(1 + 2)
substitute(x * 10)

Trait Implementations

impl CallableClone for PrimitiveSubstitute

impl CallableFormals for PrimitiveSubstitute

fn formals(&self) -> ExprList

impl Clone for PrimitiveSubstitute

fn clone(&self) -> PrimitiveSubstitute

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for PrimitiveSubstitute

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

Formats the value using the given formatter.

impl PartialEq for PrimitiveSubstitute

fn eq(&self, other: &PrimitiveSubstitute) -> 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 Sym for PrimitiveSubstitute

const SYM: &'static str = "substitute"

const KIND: &'static SymKind = _
