Enum Precedence 

pub enum Precedence {
    Left(u8),
    Right(u8),
}

Precedence information carried by a token at parse time.

Used with prec terminals to resolve operator precedence at runtime. Higher levels bind tighter. Associativity determines behavior at equal levels.

Variants

Left(u8)

Left-associative with the given level (e.g., +, -).

Right(u8)

Right-associative with the given level (e.g., =, **).

Implementations

impl Precedence

pub fn level(&self) -> u8

Get the precedence level.

Trait Implementations

impl Clone for Precedence

fn clone(&self) -> Precedence

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Precedence

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

Formats the value using the given formatter.

impl Hash for Precedence

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 Precedence

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