Struct mathemascii::GroupingExpr

pub struct GroupingExpr {
    pub left_grouping: Grouping,
    pub right_grouping: Grouping,
    pub expr: Vec<Expression>,
    pub span: Span,
}

AsciiMath grouping expression - any number of Expressions grouped between two grouping symbols, such as parentheses, brackets, etc.

Fields

left_grouping: Grouping

The opening grouping symbol.

right_grouping: Grouping

The opening grouping symbol.

expr: Vec<Expression>

The expressions inside the grouping, separated by comma.

span: Span

The span of the grouping.

Implementations

impl GroupingExpr

pub fn ignored_parentheses(self) -> Self

Replaces the grouping symbols with ignored parentheses. (See [Grouping::OpenIgnored] and [Grouping::CloseIgnored])

pub fn ungroup(self) -> Vec<Expression>

Returns the group of expressions inside the grouping without the grouping symbols.

pub fn is_empty(&self) -> bool

Checks whether the grouping contains any expressions.

pub fn len(&self) -> usize

Returns the number of expressions inside the grouping. Expressions in this case are separated by commas. That means, multiple expressions are counted as one, if they aren’t separated by a comma.

For example: (1 + 2, 3, 4) has a length of 3, because 1 + 2 is counted as one expression.

pub fn iter_inner(&self) -> impl Iterator<Item = &Expression>

Returns an iterator over the expressions between the grouping symbols.

pub fn is_simple_grp(&self) -> bool

Checks whether the grouping is one of:

• parentheses ()
• brackets []
• braces {}
• ignored {: or :}

Trait Implementations

impl Clone for GroupingExpr

fn clone(&self) -> GroupingExpr

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for GroupingExpr

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

Formats the value using the given formatter.

impl IntoElements for GroupingExpr

fn into_elements(self) -> Elements

Converts the type into elements.

impl PartialEq for GroupingExpr

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