Macro scanln::scanln

macro_rules! scanln {
    () => { ... };
    ( $($args:tt)* ) => { ... };
}

The inverse of println

Invocations of scanln expand to an expression retuning a String that contains a line of input from stdin. It can be invoked with arguments identical to those of print, and if so, those arguments will be used to generate a prompt on stdout. Input will begin on the same line that the prompt ends, if any. If no arguments are provided, input will start where the cursor is, which is likely to be on its own empty line.
