rustHow do I replace all strings in Rust?
Replacing strings in Rust is a common task and can be done using the replace
method. This method takes two parameters, the string to be replaced and the string to replace it with. For example:
let my_string = "Hello World!";
let new_string = my_string.replace("World", "Rust");
println!("{}", new_string);
Output example
Hello Rust!
The replace
method takes two parameters:
- The string to be replaced (
"World"
in the example above) - The string to replace it with (
"Rust"
in the example above)
Alternatively, you can also use the replace_all
method, which takes a regular expression as the first parameter and a string as the second parameter. This method will replace all occurrences of the regular expression with the given string.
