Function clippy_lints::needless_continue::erode_from_back

pub fn erode_from_back(s: &str) -> String

Eats at s from the end till a closing brace } is encountered, and then continues eating till a non-whitespace character is found. e.g., the string

    {
        let x = 5;
    }

is transformed to

    {
        let x = 5;

NOTE: when there is no closing brace in s, s is not preserved, i.e., an empty string will be returned in that case.
