We recommend that if you've never used Rust before, you should check out the Getting started guide in addition to the Rust book. There are also many other great tools available at the Rust learning page. You should also check out the Rust website for up-to-date information.
The TI-Nspire has many options for writing programs. The calculator officially supports Lua, and Ndless programs are typically written in C or C++. This project aims to add Rust to that list of supported languages.
Ndless is a popular program written for the TI-Nspire, which allows running arbitrary code, bypassing TI's restrictions. It has a complete toolchain for compiling, linking, and packaging TI-Nspire programs.
Rust is a modern language that's main focus is safety. For example, if
you never type the word
unsafe in your code, your program will never
segfault. It has no runtime or overhead (such as in Python, Go, Java,
JS, or C#)—just straight machine code. Its zero-cost abstractions allow
you to feel like you're writing in a high level language, but compiles
down to exactly what you would write in C or assembly. Rust was the most
loved language in the 2016, 2017, 2018, and 2019 StackOverflow Developer
Survey. In benchmarks, Rust is usually in between C and C++ in terms of
speed, but while maintaining an easy-to-use syntax with extremely
helpful error messages, that often provide the fix in the message. Rust
uses RAII, meaning that no garbage collector is needed, but there is
no need to manually allocate and free memory. Rust combines speed of
procedural languages with the ease-of-use of functional languages in
one, creating one powerful language.
As ndless does not feature a full OS, only
#![no_std]features are available. These include the core, alloc, and ndless libraries. The Rust
stdlibrary is not available. However, the ndless crate attempts to recreate as many of the features in
std. This means that any crates used will need to support
no_std. This may involve configuring special features in your
