title: Cargo
|
|
---
|
|
|
|
# Description
|
|
|
|
Cargo is Rust's build system and package manager.
|
|
|
|
# Configuration
|
|
|
|
- [Cargo.toml](20201120094652-cargo_toml)
|
|
|
|
# Commands
|
|
|
|
## Create project
|
|
|
|
``` shell
|
|
cargo new hello_cargo
|
|
```
|
|
|
|
## Build & run project
|
|
|
|
``` shell
|
|
cargo run
|
|
```
|
|
|
|
### Backtrace
|
|
|
|
When you want to see an error backtrace set the `RUST_BACKTRACE`
|
|
environment variable:
|
|
|
|
``` shell
|
|
RUST_BACKTRACE=1 cargo run
|
|
```
|
|
|
|
## Publish to Crates.io
|
|
|
|
``` shell
|
|
cargo publish
|
|
```
|
|
|
|
## Install package
|
|
|
|
``` shell
|
|
cargo install ripgrep
|
|
```
|
|
|
|
## Linting & testing
|
|
|
|
Check code
|
|
|
|
``` shell
|
|
cargo check
|
|
```
|
|
|
|
Testing
|
|
|
|
``` shell
|
|
cargo test
|
|
```
|
|
|
|
1. Backtrace
|
|
|
|
To backtrace set the `RUST_BACKTRACE` environment variable:
|
|
|
|
``` shell
|
|
RUST_BACKTRACE=1 cargo run
|
|
```
|
|
|
|
2. Threads
|
|
|
|
By default cargo runs test in parallel. For more control over this
|
|
you can pass the number of threads you want to use. For example to
|
|
only use 1 thread:
|
|
|
|
``` shell
|
|
cargo test -- --test=threads=1
|
|
```
|
|
|
|
3. Show output for passing tests as well as failed tests
|
|
|
|
``` shell
|
|
cargo test -- --show-output
|
|
```
|
|
|
|
4. Pass test name to cargo (this equals test function name)
|
|
|
|
``` shell
|
|
cargo test one_hundred
|
|
```
|
|
|
|
5. Run ignored tests
|
|
|
|
``` shell
|
|
cargo test -- --ignored
|
|
```
|
|
|
|
Fix
|
|
|
|
The rustfix tool is included with Rust installations and can
|
|
automatically fix some compiler warnings.
|
|
|
|
``` shell
|
|
cargo fix
|
|
```
|
|
|
|
## Builds
|
|
|
|
### Profiles
|
|
|
|
In Rust, release profiles are predefined and customizable profiles with
|
|
different configurations that allow a programmer to have more control
|
|
over various options for compiling code. Each profile is configured
|
|
independently of the others.
|
|
|
|
Cargo has two main profiles: the `dev` profile Cargo uses when you run
|
|
cargo build and the release profile Cargo uses when you run
|
|
`cargo build --release`. The `dev` profile is defined with good defaults
|
|
for development, and the `release` profile has good defaults for release
|
|
builds.
|
|
|
|
1. dev
|
|
|
|
``` shell
|
|
cargo build
|
|
```
|
|
|
|
2. build
|
|
|
|
``` shell
|
|
cargo build --release
|
|
```
