Struct Prec 

pub struct Prec(pub u32);

Numeric precedence for an operator.

Tuple Fields

0: u32

Implementations

impl Prec

pub const ATOM: Prec

Default term precedence (Lean 4 uses 1024 for atoms).

pub const APP: Prec

Precedence for function application.

pub const MUL: Prec

Precedence for * / /.

pub const ADD: Prec

Precedence for + / -.

pub const CMP: Prec

Precedence for comparison operators.

pub const MIN: Prec

Minimum precedence (weakest binding).

pub fn new(p: u32) -> Self

Create a precedence value.

pub fn value(self) -> u32

Raw numeric value.

pub fn tighter(self) -> Self

One level tighter binding.

Trait Implementations

impl Clone for Prec

fn clone(&self) -> Prec

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Prec

impl Debug for Prec

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

Formats the value using the given formatter.

impl Display for Prec

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

impl Eq for Prec

impl Hash for Prec

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 Ord for Prec

fn cmp(&self, other: &Prec) -> 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 Prec

fn eq(&self, other: &Prec) -> bool

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for Prec

fn partial_cmp(&self, other: &Prec) -> 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.
