Struct PrecLevel 

pub struct PrecLevel {
    pub value: u32,
    pub left_assoc: bool,
    pub right_assoc: bool,
}

A notation precedence level with associativity.

Fields

value: u32

The precedence value (higher = tighter binding)

left_assoc: bool

Whether this is left-associative

right_assoc: bool

Whether this is right-associative

Implementations

impl PrecLevel

pub fn left(value: u32) -> Self

Create a new left-associative precedence level.

pub fn right(value: u32) -> Self

Create a new right-associative precedence level.

pub fn none(value: u32) -> Self

Create a non-associative level.

Trait Implementations

impl Clone for PrecLevel

fn clone(&self) -> PrecLevel

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PrecLevel

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

Formats the value using the given formatter.

impl PartialEq for PrecLevel

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