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: .TP \fB:help\fR Display a summary of available commands. .TP \fB:{\\n ..lines.. \\n:}\\n\fR execute multiline command .TP \fB:load <crate> ...\fR loads given crates as dynamic libraries .TP \fB:clear\fR clear the bindings .TP \fB:exit\fR exit from the repl .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 .Ve .SH "SEE ALSO" rust, rustc, rustdoc, rustpkg .SH "BUGS" See <\fBhttps://github.com/mozilla/rust/issues\fR> for issues. .SH "AUTHOR" See \fBAUTHORS.txt\fR in the rust source distribution.
