Enum BindingPower 

pub enum BindingPower {
    Base,
    Or,
    And,
    Equality,
    Relation,
    AddSub,
    MulDiv,
    Power,
    Nullish,
    Prefix,
    Range,
    Call,
    Prime,
}

An enum which defines how strong a operator binds it’s operands.

If a binding power is higher the operator is more likely to directly operate on it’s neighbours.

Implementations

impl BindingPower

pub fn for_binary_operator(op: &BinaryOperator) -> Self

Returns the binding power of this operator.

Note that there are some variants here which can have multiple meanings. Operator::Equal can be assignment but can also be equality. Operator::Add can be the add operator but also the plus prefix operator which have different binding powers.

This function returns the binding power for if the operator is used in the infix position.

pub fn for_postfix_operator(op: &PostfixOperator) -> Self

pub fn for_prefix_operator(op: &PrefixOperator) -> Self

pub fn for_expr(expr: &Expr) -> BindingPower

Returns the binding power for this expression. This is generally BindingPower::Prime as most value variants are prime expressions, however some like Value::Expression and Value::Range have a different binding power.

Trait Implementations

impl Clone for BindingPower

fn clone(&self) -> BindingPower

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BindingPower

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

Formats the value using the given formatter.

impl Ord for BindingPower

fn cmp(&self, other: &BindingPower) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for BindingPower

fn eq(&self, other: &BindingPower) -> 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 PartialOrd for BindingPower

fn partial_cmp(&self, other: &BindingPower) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
