.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.
|
||
