no_std_data

You can see this text along with additional content and source code sections in a presentation. That also shows any source code referred to below. —

Goal

Examples of no_std (low level/embedded-friendly) and mostly heapless & slice-handling patterns in Rust.

Prerequisites

https://peter-kehl.github.io/no_std_rust_lib_presentation
nightly Rust (July 2022), but only for test purposes. The actual implementations work with stable.

Disclaimers

Disambiguation

This is not about DNA/RNA/genetic patterns in general or at any detail. Instead, it’s a set of implementations of Exercism > Rust Track > RNA Transcription exercise.

Omitted & non-standard documentation

Big parts of these examples are repetitive. For brevity, similar items are docummented only once: at their first occurrence (as in the above order of the examples).

Some code documentation comments include implementation details, or they refer to private fields/functions. That’s contrary to a general good practice of API design/documentation. However, this allows the reader to easily navigate to Rust API references (for example, by Ctrl+click in VS Code).

Exercism-specific disclaimer

Two implementations required a minor change to its Exercism’s tests.

In order to upload this to Exercism, you’d need to

incorporate 00_shared/src/lib.rs into src/lib.rs of your chosen solution,
change your (chosen implementation) crate name back to rna_transcription in its Cargo.toml and in its tests/rna-transcription.rs; and
rename the crate’s directory to rna-transcription.
