Is string trim() faulty or am I not using it correctly?

[garypen]

I ran:

fn run(hello) {
    print(hello);
    print(hello.trim());
}
run("    hello   ");

in the rhai playground and saw:

Waiting for Web Worker to finish loading...
Running script at 2022-03-17T08:18:27.440Z

[PRINT]     hello   
[PRINT] 

Script returned: ""
Finished at 2022-03-17T08:18:27.443Z

which surprised me.

bug?

trim modifies the string inline.

Try:

fn run(hello) {
    print(hello);
    hello.trim();
    print(hello);
}
run("    hello   ");

Turns out the doc-comments for trim has an incorrect example. It is now fixed.

Thanks very much for the info. I'll close this.
