Trait Implementations

impl Compiler for UnaryOp

fn compile(&self, pslab: &ParseSlab, cslab: &mut CompileSlab) -> Instruction

Turns a parsed Expression into a compiled Instruction.

impl Debug for UnaryOp

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

Formats the value using the given formatter.

impl Evaler for UnaryOp

fn _var_names(&self, slab: &Slab, dst: &mut BTreeSet<String>)

Don’t call this directly. Use var_names() instead.

fn eval(&self, slab: &Slab, ns: &mut impl EvalNamespace) -> Result<f64, Error>

Evaluate this Expression/Instruction and return an f64.

fn var_names(&self, slab: &Slab) -> BTreeSet<String>

Returns a list of variables and custom functions that are used by this Expression/Instruction.

impl PartialEq for UnaryOp

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