Trait AssertStringPattern

pub trait AssertStringPattern<E> {
    // Required methods
    fn contains(self, pattern: E) -> Self;
    fn starts_with(self, pattern: E) -> Self;
    fn ends_with(self, pattern: E) -> Self;
}

Assert that a string contains a substring or character.

Examples

use asserting::prelude::*;

let subject = "doming vulputate proident eum";

assert_that!(subject).contains("tate p");
assert_that!(subject).contains('u');
assert_that!(subject).starts_with("dom");
assert_that!(subject).starts_with('d');
assert_that!(subject).ends_with("t eum");
assert_that!(subject).ends_with('m');

Required Methods

fn contains(self, pattern: E) -> Self

Verifies that a string contains a substring or character.

Examples

use asserting::prelude::*;

let subject = "doming vulputate proident eum";

assert_that!(subject).contains("tate p");
assert_that!(subject).contains('u');

fn starts_with(self, pattern: E) -> Self

Verifies that a string starts with a substring or character.

Examples

use asserting::prelude::*;

let subject = "doming vulputate proident eum";

assert_that!(subject).starts_with("dom");
assert_that!(subject).starts_with('d');

fn ends_with(self, pattern: E) -> Self

Verifies that a string ends with a substring or character.

Examples

use asserting::prelude::*;

let subject = "doming vulputate proident eum";

assert_that!(subject).ends_with("t eum");
assert_that!(subject).ends_with('m');

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
