# `splice`

The tracking issue for this feature is: #44643

The `splice()` method on `String` allows you to replace a range of values in a string with another range of values.

A simple example:

    # #![allow(unused_variables)]
    #![feature(splice)]
    #fn main() {
    let mut s = String::from("α is alpha, β is beta");
    let beta_offset = s.find('β').unwrap_or(s.len());

    // Replace the range up until the β from the string
    s.splice(..beta_offset, "Α is capital alpha; ");
    assert_eq!(s, "Α is capital alpha; β is beta");
    #}
