Enum MathConstant 

pub enum MathConstant {
    Pi,
    E,
    I,
    Infinity,
    NegInfinity,
}

Mathematical constants used in expressions.

These represent well-known mathematical constants with precise mathematical meaning.

Examples

use mathlex::ast::MathConstant;

let pi = MathConstant::Pi;
let euler = MathConstant::E;
assert_ne!(pi, euler);

Variants

Pi

The mathematical constant π (pi), approximately 3.14159…

E

Euler’s number e, approximately 2.71828…

I

The imaginary unit i, where i² = -1

Infinity

Positive infinity (∞)

NegInfinity

Negative infinity (-∞)

Trait Implementations

impl Clone for MathConstant

fn clone(&self) -> MathConstant

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MathConstant

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

Formats the value using the given formatter.

impl Display for MathConstant

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

Formats the value using the given formatter.

impl Hash for MathConstant

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for MathConstant

fn eq(&self, other: &MathConstant) -> 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 ToLatex for MathConstant

fn to_latex(&self) -> String

Converts the value to a LaTeX string.

impl Copy for MathConstant

impl Eq for MathConstant

impl StructuralPartialEq for MathConstant
