| .SH DESCRIPTION |
| |
| This program is a REPL (Read-Eval-Print Loop) for the Rust language, available |
| at <\fBhttps://www.rust-lang.org\fR>. It provides an interactive shell to |
| evaluate Rust expressions, functions and code snippets, and to experiment with |
| Rust code. |
| |
| .B WARNING: |
| The Rust REPL is experimental and may be unstable. If you encounter problems, |
| please use the compiler instead. |
| |
| .SH OPTIONS |
| |
| Currently none. |
| |
| .SH SPECIAL COMMANDS |
| |
| The interactive shell evaluates all input as a sequence of Rust expressions, |
| except for a set of special commands prefixed by a colon ':'. These special |
| commands are described below: |

| .SH "EXAMPLES" |
| |
| A simple example session, declaring a variable, defining a function, |
| evaluating an expression and printing the result: |
| |
| .PP |
| .Vb |
| \& \fBrusti>\fR let x = 42; |
| \& \fBrusti>\fR fn square(n: int) -> int { n*n } |
| \& \fBrusti>\fR println(fmt!("%d squared is %d", x, square(x))); |
| \& 42 squared is 1764 |
