## Customizing Builds with Release Profiles
|
|||
|
|
|
|||
|
|
=> Release profiles are predefined and customizable profiles with different configurations that allow a programmer to have more control over various options for compiling code.
|
|||
|
|
|
|||
|
|
Cargo has 2 main profiles:
|
|||
|
|
|
|||
|
|
- `dev`: for development (used by default with `cargo build`)
|
|||
|
|
- `release`: for release (used with `cargo build --release`)
|
|||
|
|
|
|||
|
|
We can customize the `release` profile by adding a section to the `Cargo.toml` file:
|
|||
|
|
|
|||
|
|
```toml
|
|||
|
|
[profile.dev]
|
|||
|
|
opt-level = 0
|
|||
|
|
|
|||
|
|
[profile.release]
|
|||
|
|
opt-level = 3
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
## Publishing a Crate to Crates.io
|
|||
|
|
|
|||
|
|
Packages can be published to [crates.io](https://crates.io/), the Rust community’s package registry.
