How can I return a vector of strings by splitting a string that has spaces in between
fn line_to_words(line: &str) -> Vec<String> {
line.split_whitespace().collect()
}
fn main() {
println!( "{:?}", line_to_words( "string with spaces in between" ) );
}
You need to transform the iterator's item type from &str
to String
; for example, by doing
line.split_whitespace().map(str::to_string).collect()
You can also map From::from
or Into::into
to achieve the same result.

In this case it's possible to return views into the original input string, so you can return Vec<&str>
.
