Struct chalk_engine::TimeStamp

pub struct TimeStamp { /* fields omitted */ }

The “time stamp” is a simple clock that gets incremented each time we encounter a positive answer in processing a particular strand. This is used as an optimization to help us figure out when we may have changed inference variables.

Trait Implementations

impl Clone for TimeStamp

fn clone(&self) -> TimeStamp

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TimeStamp

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

Formats the value using the given formatter.

impl Default for TimeStamp

fn default() -> TimeStamp

Returns the “default value” for a type.

impl<I: Interner> Fold<I> for TimeStamp

type Result = Self

The type of value that will be produced once folding is done. Typically this is Self, unless Self contains borrowed values, in which case owned values are produced (for example, one can fold over a &T value where T: Fold, in which case you get back a T, not a &T).

fn fold_with<'i>(
    self,
    _folder: &mut dyn Folder<'i, I>,
    _outer_binder: DebruijnIndex
) -> Fallible<Self::Result> where
    I: 'i, 

Apply the given folder folder to self; binders is the number of binders that are in scope when beginning the folder. Typically binders starts as 0, but is adjusted when we encounter Binders<T> in the IR or other similar constructs.

impl Hash for TimeStamp

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, 

Feeds a slice of this type into the given Hasher.

impl Ord for TimeStamp

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

This method returns an Ordering between self and other.

#[must_use]

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

Compares and returns the maximum of two values.

#[must_use]

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

Compares and returns the minimum of two values.

#[must_use]

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

Restrict a value to a certain interval.

impl PartialEq<TimeStamp> for TimeStamp

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=.

impl PartialOrd<TimeStamp> for TimeStamp

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

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

#[must_use]

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

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

#[must_use]

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

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

#[must_use]

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

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

#[must_use]

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

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

impl<I: Interner> Visit<I> for TimeStamp

fn visit_with<'i, B>(
    &self,
    _visitor: &mut dyn Visitor<'i, I, BreakTy = B>,
    _outer_binder: DebruijnIndex
) -> ControlFlow<B> where
    I: 'i, 

Apply the given visitor visitor to self; binders is the number of binders that are in scope when beginning the visitor. Typically binders starts as 0, but is adjusted when we encounter Binders<T> in the IR or other similar constructs.
