Rna Transcription in Rust
Given a DNA strand, return its RNA Complement Transcription.
exercism fetch rust rna-transcription
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:
Notes on Rust implementation
By using private fields in structs with public
new functions returning
Result (as here with
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
This explains the type signatures you will see in the tests.

Writing the Code
Execute the tests with:
$ cargo test
All but the first test have been ignored. After you get the first test to
pass, open the tests source file wich is located in the
and remove the
#[ignore] flag from the next test and get the tests to pass
again. Each separate test is a function with
#[test] flag above it.
Continue, until you pass every test.
If you wish to run all tests without editing the tests source file, use:
$ cargo test -- --ignored
To run a specific test, for example
some_test, you can use:
$ cargo test some_test
If the specfic test is ignored use:
$ cargo test some_test -- --ignored
To learn more about Rust tests refer to the online test documentation
Make sure to read the Modules chapter if you haven't already, it will help you with organizing your files.
