RNA Transcription

Welcome to RNA Transcription on Exercism's Rust Track. If you need help running the tests or submitting your code, check out HELP.md.

Instructions

Given a DNA strand, return its RNA complement (per RNA transcription).

Both DNA and RNA strands are a sequence of nucleotides.

The four nucleotides found in DNA are adenine (A), cytosine (C), guanine (G) and thymine (T).

The four nucleotides found in RNA are adenine (A), cytosine (C), guanine (G) and uracil (U).

Given a DNA strand, its transcribed RNA strand is formed by replacing each nucleotide with its complement:

G -> C
C -> G
T -> A
A -> U

By using private fields in structs with public new functions returning Option or Result (as here with DNA::new & RNA::new), we can guarantee that the internal representation of DNA is correct. Because every valid DNA string has a valid RNA string, we don't need to return a Result/Option from into_rna.

This explains the type signatures you will see in the tests.
