Enum chumsky::pratt::Associativity

pub enum Associativity {
    Left(u16),
    Right(u16),
}

Available on crate feature pratt only.

Defines the associativity and binding power of an infix operator (see left and right).

Higher binding powers should be used for higher precedence operators.

Variants

Left(u16)

Specifies that the operator should be left-associative, with the given binding power (see left).

Right(u16)

Specifies that the operator should be right-associative, with the given binding power (see right).

Trait Implementations

impl Clone for Associativity

fn clone(&self) -> Associativity

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Associativity

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

Formats the value using the given formatter.

impl Ord for Associativity

fn cmp(&self, other: &Associativity) -> 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 + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for Associativity

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

impl PartialOrd for Associativity

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

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

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

This method tests less than (for self and other) and is used by the < operator.

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

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

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

This method tests greater than (for self and other) and is used by the > operator.

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

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