# Cargo B(inary)Install
|
|
|
|
`cargo binstall` provides a low-complexity mechanism for installing rust binaries as an alternative to building from source (via `cargo install`) or manually downloading packages. This is intended to work with existing CI artifacts and infrastructure, and with minimal overhead for package maintainers.
|
|
|
|
`binstall` works by fetching the crate information from `crates.io`, then searching the linked `repository` for matching releases and artifacts, with fallbacks to [quickinstall](https://github.com/alsuren/cargo-quickinstall) and finally `cargo install` if these are not found.
|
|
To support `binstall` maintainers must add configuration values to `Cargo.toml` to allow the tool to locate the appropriate binary package for a given version and target. See [SUPPORT.md](./SUPPORT.md) for more detail.

## Installation
|
|
|
|
To get started _using_ `cargo-binstall` first install the binary (either via `cargo install cargo-binstall` or by downloading a pre-compiled [release](https://github.com/ryankurte/cargo-binstall/releases)).

## Usage
|
|
|
|
Supported packages can be installed using `cargo binstall NAME` where `NAME` is the crates.io package name.
|
|
|
|
Package versions and targets may be specified using the `--version` and `--target` arguments respectively, and will be installed into `$HOME/.cargo/bin` by default. For additional options please see `cargo binstall --help`.

|
### Unsupported crates
|
|
|
|
To install an unsupported crate, you may specify the Cargo.toml metadata entries for `pkg-url`, `bin-dir`, and `pkg-fmt` at the command line, with values [as documented below](#supporting-binary-installation).
|
|
|
|
For example:
|
|
```
|
|
$ binstall \
|
|
--pkg-url="{ repo }/releases/download/{ version }/{ name }-{ version }-{ target }.{ archive-format }" \
|
|
--pkg-fmt="txz" crate_name
|
|
```

## FAQ
|
|
|
|
- Why use this?
|
|
- Because `wget`-ing releases is frustrating, `cargo install` takes a not inconsequential portion of forever on constrained devices,
|
|
and often putting together actual _packages_ is overkill.
|
|
- Why use the cargo manifest?
|
|
- Crates already have these, and they already contain a significant portion of the required information.
|
|
Also there's this great and woefully underused (imo) `[package.metadata]` field.
|
|
- Is this secure?
|
|
- Yes and also no? We're not (yet? [#1](https://github.com/cargo-bins/cargo-binstall/issues/1)) doing anything to verify the CI binaries are produced by the right person / organisation.
|
|
However, we're pulling data from crates.io and the cargo manifest, both of which are _already_ trusted entities, and this is
|
|
functionally a replacement for `curl ... | bash` or `wget`-ing the same files, so, things can be improved but it's also fairly moot
|
|
- What do the error codes mean?
|
|
- You can find a full description of errors including exit codes here: <https://docs.rs/cargo-binstall/latest/cargo_binstall/errors/enum.BinstallError.html>
