readchar

a concurrently outputting readline implementation

Example

see ./examples/generic.rs for example usage

cargo run --example generic.rs -- executable args

executes executable with args, and then the input line from readchar is the final argument, so

cargo run --example generic.rs -- calc

will run calc on each input line while you type
