Struct predicates::path::ExistencePredicate

pub struct ExistencePredicate { /* private fields */ }

Predicate that checks if a file is present

This is created by the predicate::path::exists and predicate::path::missing.

Trait Implementations

impl Clone for ExistencePredicate

fn clone(&self) -> ExistencePredicate

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ExistencePredicate

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

Formats the value using the given formatter.

impl Display for ExistencePredicate

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

Formats the value using the given formatter.

impl PartialEq<ExistencePredicate> for ExistencePredicate

fn eq(&self, other: &ExistencePredicate) -> 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 Predicate<Path> for ExistencePredicate

fn eval(&self, path: &Path) -> bool

Execute this Predicate against variable, returning the resulting boolean.

fn find_case<'a>(&'a self, expected: bool, variable: &Path) -> Option<Case<'a>>

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

impl PredicateReflection for ExistencePredicate

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

Parameters of the current Predicate.

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

Nested Predicates of the current Predicate.
