$PRGNAM: $PRGNAM (a safe, concurrent, practical language)
$PRGNAM:
$PRGNAM:  Rust is a curly-brace, block-structured expression language.
$PRGNAM: It visually resembles the C language family, but differs significantly in
$PRGNAM: syntactic and semantic details. Its design is oriented toward concerns of
$PRGNAM: “programming in the large”, that is, of creating and maintaining boundaries
$PRGNAM: – both abstract and operational – that preserve large-system integrity,
$PRGNAM: availability and concurrency.
