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

pub fn clone(&self) -> TimeStamp

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Copy for TimeStamp

impl Debug for TimeStamp

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

Formats the value using the given formatter.

impl Default for TimeStamp

pub fn default() -> TimeStamp

Returns the "default value" for a type.

impl Eq for TimeStamp

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).

pub 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

pub fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

pub 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

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

This method returns an Ordering between self and other.

#[must_use]pub fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

#[must_use]pub fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

#[must_use]pub fn clamp(self, min: Self, max: Self) -> Self

🔬 This is a nightly-only experimental API. (clamp)

Restrict a value to a certain interval.

impl PartialEq<TimeStamp> for TimeStamp

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

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

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

This method tests for !=.

impl PartialOrd<TimeStamp> for TimeStamp

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

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

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

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

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

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

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

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

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

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

impl StructuralEq for TimeStamp

impl StructuralPartialEq for TimeStamp

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

pub 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.
