Struct predicates::str::ContainsPredicate

pub struct ContainsPredicate { /* fields omitted */ }

Predicate that checks for patterns.

This is created by predicates::str:contains.

Methods

impl ContainsPredicate

pub fn count(self, count: usize) -> MatchesPredicate

Require a specific count of matches.

Examples

use predicates::prelude::*;

let predicate_fn = predicate::str::contains("Two").count(2);
assert_eq!(true, predicate_fn.eval("One Two Three Two One"));
assert_eq!(false, predicate_fn.eval("One Two Three"));

Trait Implementations

impl Eq for ContainsPredicate

impl PartialEq<ContainsPredicate> for ContainsPredicate

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

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

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

This method tests for !=.

impl Clone for ContainsPredicate

fn clone(&self) -> ContainsPredicate

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Display for ContainsPredicate

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

Formats the value using the given formatter.

impl Debug for ContainsPredicate

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

Formats the value using the given formatter.

impl Predicate<str> for ContainsPredicate

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

Execute this Predicate against variable, returning the resulting boolean.

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

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

impl PredicateReflection for ContainsPredicate

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

Parameters of the current Predicate.

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