Enum mathemascii::SimpleExpr

pub enum SimpleExpr {
    Var(Var),
    Grouping(GroupingExpr),
    Unary(Unary),
    Binary(Binary),
    Interm(Box<Expression>),
}

Simple AsciiMath expression that can be one of the following:

• Variable - any number, identifier, greek letter etc.
• Grouping - any number of expressions surrounded by parentheses, brackets, braces etc.
• Unary - unary operator applied to an expression, i.e. sqrt(a).
• Binary - binary operator applied to two expressions, i.e. root(3)(a + b).

Variants

Var(Var)

Variable - any number, identifier, greek letter etc.

Grouping(GroupingExpr)

Grouping - any number of expressions surrounded by parentheses, brackets, braces etc.

Unary(Unary)

Unary operator applied to an expression, i.e. sqrt(a).

Binary(Binary)

Binary operator applied to two expressions, i.e. root(3)(a + b).

Interm(Box<Expression>)

Intermediate expression is simply a wrapped Expression. AsciiMath differs Expression and Intermediate expression, but in this implementation they are the same. The top-level expression defined in ascii math grammar is the AsciiMath iterator that produces multiple Expressions.

Implementations

impl SimpleExpr

pub fn span(&self) -> Span

Returns the [Span] of the expression.

pub fn is_empty(&self) -> bool

Returns true if the expression contains no inner expressions.

pub fn len(&self) -> usize

Returns the number of expressions inside grouping, or 1 otherwise.

Trait Implementations

impl Clone for SimpleExpr

fn clone(&self) -> SimpleExpr

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for SimpleExpr

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

Formats the value using the given formatter.

impl IntoElements for SimpleExpr

fn into_elements(self) -> Elements

Converts the type into elements.

impl PartialEq for SimpleExpr

fn eq(&self, other: &SimpleExpr) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
