Trait for set assertion.

Example

use assertor::*;
use std::collections::HashSet;

let mut set = HashSet::new();
assert_that!(set).is_empty();

set.insert("a");
set.insert("b");
set.insert("c");

assert_that!(set).contains("a");
assert_that!(set).has_length(3);

use assertor::*;
use std::collections::HashSet;

let mut set = HashSet::new();
set.insert("a");
assert_that!(set).contains("z");
// expected to contain  : "z"
// but did not
// though it did contain: ["a"]

Required Methods

fn has_length(&self, length: usize) -> R

Checks that the subject has the given length.

fn is_empty(&self) -> Rwhere T: Debug,

Checks that the subject is empty.

fn contains<B: Borrow<T>>(&self, expected: B) -> Rwhere T: PartialEq + Eq + Debug + Hash,

Checks that the subject has expected.

fn does_not_contain<B>(&self, element: B) -> Rwhere B: Borrow<T>, T: PartialEq + Debug,

Checks that the subject does not contain element.

fn does_not_contain_any<B: Borrow<Vec<T>>>(&self, elements: B) -> Rwhere T: PartialEq + Debug,

Checks that the subject does not contain any element of elements.
