# Workflow to build your docs with oranda (and mdbook)

name: Web
# We're going to push to the gh-pages branch, so we need that permission
permissions:
contents: write
# What situations do we want to build docs in?
# All of these work independently and can be removed / commented out
# if you don't want oranda/mdbook running in that situation
on:
# Check that a PR didn't break docs!
#
# Note that the "Deploy to Github Pages" step won't run in this mode,
# so this won't have any side-effects. But it will tell you if a PR
# completely broke oranda/mdbook. Sadly we don't provide previews (yet)!
pull_request:
# Whenever something gets pushed to main, update the docs!
# This is great for getting docs changes live without cutting a full release.
#
# Note that if you're using cargo-dist, this will "race" the Release workflow
# that actually builds the Github Release that oranda tries to read (and
# this will almost certainly complete first). As a result you will publish
# docs for the latest commit but the oranda landing page won't know about
# the latest release. The workflow_run trigger below will properly wait for
# cargo-dist, and so this half-published state will only last for ~10 minutes.
#
# If you only want docs to update with releases, disable this, or change it to
# a "release" branch. You can, of course, also manually trigger a workflow run
# when you want the docs to update.
push:
branches:
- main
# Whenever a workflow called "Release" completes, update the docs!
#
# If you're using cargo-dist, this is recommended, as it will ensure that
# oranda always sees the latest release right when it's available. Note
# however that Github's UI is wonky when you use workflow_run, and won't
# show this workflow as part of any commit. You have to go to the "actions"
# tab for your repo to see this one running (the gh-pages deploy will also
# only show up there).

## Enabling `rust-analyzer` ## Enabling `rust-analyzer`
Run the command `rustlings lsp` which will generate a `rust-project.json` at the root of the project, this allows [rust-analyzer](https://rust-analyzer.github.io/) to parse each exercise. `rust-analyzer` support is provided, but it depends on your editor
whether it's enabled by default. (RLS support is not provided)
To enable `rust-analyzer`, you'll need to make Cargo build the project
with the `exercises` feature, which will automatically include the `exercises/`
subfolder in the project. The easiest way to do this is to tell your editor to
build the project with all features (the equivalent of `cargo build --all-features`).
For specific editor instructions:
- **VSCode**: Add a `.vscode/settings.json` file with the following:
```json
{
"rust-analyzer.cargo.features": ["exercises"]
}
```
- **IntelliJ-based Editors**: Using the Rust plugin, everything should work
by default.

## Completion
Rustlings isn't done; there are a couple of sections that are very experimental and don't have proper documentation. These include:
- Errors (`exercises/errors/`)
- Option (`exercises/option/`)
- Result (`exercises/result/`)
- Move Semantics (could still be improved, `exercises/move_semantics/`)
Additionally, we could use exercises on a couple of topics:
- Structs
- Better ownership stuff
- `impl`
- ??? probably more
If you are interested in improving or adding new ones, please feel free to contribute! Read on for more information :)

# Collections
Rusts standard library includes a number of very useful data
structures called collections. Most other data types represent one
specific value, but collections can contain multiple values. Unlike
the built-in array and tuple types, the data these collections point
to is stored on the heap, which means the amount of data does not need
to be known at compile time and can grow or shrink as the program
runs.
This exercise will get you familiar with two fundamental data
structures that are used very often in Rust programs:
* A *vector* allows you to store a variable number of values next to
each other.
* A *hash map* allows you to associate a value with a particular key.
You may also know this by the names [*unordered map* in C++](https://en.cppreference.com/w/cpp/container/unordered_map),
[*dictionary* in Python](https://docs.python.org/3/tutorial/datastructures.html#dictionaries) or an *associative array* in other languages.

# Lifetimes
Lifetimes tell the compiler how to check whether references live long
enough to be valid in any given situation. For example lifetimes say
"make sure parameter 'a' lives as long as parameter 'b' so that the return
value is valid".
They are only necessary on borrows, i.e. references,
since copied parameters or moves are owned in their scope and cannot
be referenced outside. Lifetimes mean that calling code of e.g. functions
can be checked to make sure their arguments are valid. Lifetimes are
restrictive of their callers.
If you'd like to learn more about lifetime annotations, the
[lifetimekata](https://tfpk.github.io/lifetimekata/) project
has a similar style of exercises to Rustlings, but is all about
learning to write lifetime annotations.
