[](https://crates.io/crates/codetrotter_aoc_2019_solutions)
My solutions for [Advent of Code 2019](https://adventofcode.com/2019/).
You'll need the Rust toolchain to build from source – get it from
the official site at https://rustup.rs. I am currently using
Rust stable version 1.40.0 (cargo 1.40.0 bc8e4c8be 2019-11-22 +
rustc 1.40.0 73528e339 2019-12-16).

## Docs
```bash
cargo doc --lib --no-deps --release --target-dir ../aoc-2019-docs/ --open
```
https://ctsrc.github.io/aoc-2019/doc/codetrotter_aoc_2019_solutions/
## Running tests
```bash
cargo test
```
## Clippy lints
```bash
cargo clean ; cargo clippy -- \
-A clippy::suspicious_else_formatting \
-A clippy::unreadable_literal \
-A clippy::unnecessary_mut_passed
```
Then pick one of the things it complains about and look at all instances of only that.
For example:
```bash
touch src/lib.rs ; cargo clippy -- -A clippy::all -W clippy::trivially_copy_pass_by_ref
```
## Running solutions
### Running solution for highest day number solved
```bash
cargo run
```
### Running solutions for all solved days with both parts
```bash
cargo run -- -a
```
### Running solutions for selected days
Both parts of some day, for example day 3
```bash
cargo run -- days 3
```
Part one of some day, for example day 3 part 1
```bash
cargo run -- days 3.1
```
Part two of some day, for example day 3 part 2
```bash
cargo run -- days 3.2
```
Both parts of each of multiple days, for example days 1, 2 and 3
```bash
cargo run -- days 1 2 3
```
Selected parts of multiple days, for example day 3 part 1
and day 2 part 2 along with both parts of day 1.
```bash
cargo run -- days 3.1 2.2 1
```
