To remove all whitespace characters from a string in Rust, you can use the `chars` method to iterate through characters and filter out whitespace characters.
In this example,
str
with a value of "Hello World"
.chars
method and filter out whitespace characters.modified_str
.modified_str
.fn main() {
let str = "Hello World";
let modified_str: String = str.chars()
.filter(|&c| !c.is_whitespace())
.collect();
println!("Modified string: {}", modified_str);
}
Modified string: HelloWorld
In this example,
str
with a value of "apple\tbanana\n cherry "
.chars
method and filter out whitespace characters.modified_str
.modified_str
.fn main() {
let str = "apple\tbanana\n cherry ";
let modified_str: String = str.chars()
.filter(|&c| !c.is_whitespace())
.collect();
println!("Modified string: {}", modified_str);
}
Modified string: applebananacherry
