echo

FUNCTIONAL CLONE of Bash's built-in echo, except it ALWAYS HAS -e support (where Bash and even GNU echo can be put into POSIX mode with no -e support).

Rust and C

These are two completely different project folders. They are independent, and have been tested to be sure they behave the same way.

The approach was slightly different with each, partly because of the way Rust is very protective about variable ownership.

Requires...

The C version requires gcc gnu99 compatible compiler. That is any gcc on Linux or Apple OS X. On Apple OS X, you only need the Xcode Command Line Tools, not the whole Xcode package.

The Rust version requires cargo and rustc that supports spec 2021, though you may have luck adjusting that down, as this is my first Rust project, I've left it as is.

Differences...

The C echo is version 0.03. The Rust echo is version 0.0.2.

I've found no functional differences at all, and I do some silly tests.
