rustHow to match the end of a line in a Rust regex?

To match the end of a line in a Rust regex, use the $ character. This character matches the end of a line, regardless of the line ending character. For example:

let re = Regex::new(r"end$").unwrap();
assert!(re.is_match("This is the end"));
assert!(!re.is_match("This is not the end."));

The code above creates a new regex object with the pattern end$. The $ character at the end of the pattern indicates that the pattern should match the end of the line. The code then tests two strings to see if they match the pattern. The first string, This is the end, matches the pattern because it ends with end. The second string, This is not the end., does not match the pattern because it does not end with end.

Parts of the code:

• Regex::new(r"end$"): creates a new regex object with the pattern end$
• assert!(re.is_match("This is the end")): tests if the string This is the end matches the pattern end$
• assert!(!re.is_match("This is not the end.")): tests if the string This is not the end. matches the pattern end$
