Struct TraceBound 

pub struct TraceBound<T: ?Sized>(/* private fields */);

Lower bound on keys or values in a trace.

Setting the bound to None is equivalent to setting it to T::min_value(), i.e., the contents of the trace will never get truncated.

The writer can update the value of the bound at each clock cycle. The bound can only increase monotonically.

Implementations

impl<K: DataTrait + ?Sized> TraceBound<K>

pub fn new() -> Self

pub fn set(&self, bound: Box<K>)

Set the new value of the bound.

pub fn get(&self) -> Ref<'_, Option<Box<K>>>

Get the current value of the bound.

Trait Implementations

impl<T: DataTrait + ?Sized> Clone for TraceBound<T>

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T: Debug + ?Sized> Debug for TraceBound<T>

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

Formats the value using the given formatter.

impl<K: DataTrait + ?Sized> Default for TraceBound<K>

fn default() -> Self

Returns the “default value” for a type.

impl<T: DataTrait + ?Sized> Ord for TraceBound<T>

fn cmp(&self, other: &Self) -> 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<T: DataTrait + ?Sized> PartialEq for TraceBound<T>

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

impl<T: DataTrait + ?Sized> PartialOrd for TraceBound<T>

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