Struct tracing_capture::predicates::ParentPredicate

pub struct ParentPredicate<P> { /* private fields */ }

Predicate for the parent of a CapturedSpan or CapturedEvent returned by the parent() function.

Trait Implementations

impl<Rhs, P> BitAnd<Rhs> for ParentPredicate<P>

where Self: PredicateReflection, Rhs: PredicateReflection,

type Output = And<ParentPredicate<P>, Rhs>

The resulting type after applying the & operator.

fn bitand(self, rhs: Rhs) -> Self::Output

Performs the & operation.

impl<Rhs, P> BitOr<Rhs> for ParentPredicate<P>

where Self: PredicateReflection, Rhs: PredicateReflection,

type Output = Or<ParentPredicate<P>, Rhs>

The resulting type after applying the | operator.

fn bitor(self, rhs: Rhs) -> Self::Output

Performs the | operation.

impl<P: Clone> Clone for ParentPredicate<P>

fn clone(&self) -> ParentPredicate<P>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<P: Debug> Debug for ParentPredicate<P>

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

Formats the value using the given formatter.

impl<P> Display for ParentPredicate<P>

where P: for<'a> Predicate<CapturedSpan<'a>>,

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

Formats the value using the given formatter.

impl<P: PartialEq> PartialEq for ParentPredicate<P>

fn eq(&self, other: &ParentPredicate<P>) -> bool

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

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<'a, P, T> Predicate<T> for ParentPredicate<P>

where T: Captured<'a>, P: for<'p> Predicate<CapturedSpan<'p>>,

fn eval(&self, variable: &T) -> bool

Execute this Predicate against variable, returning the resulting boolean.

fn find_case(&self, expected: bool, variable: &T) -> Option<Case<'_>>

Find a case that proves this predicate as expected when run against variable.

impl<P> PredicateReflection for ParentPredicate<P>

where P: for<'a> Predicate<CapturedSpan<'a>>,

fn parameters<'a>(&'a self) -> Box<dyn Iterator<Item = Parameter<'a>> + 'a>

Parameters of the current Predicate.

fn children<'a>(&'a self) -> Box<dyn Iterator<Item = Child<'a>> + 'a>

Nested Predicates of the current Predicate.
