Docs.rs (formerly cratesfyi) is an open source project to host documentation of crates for the Rust Programming Language.
Docs.rs automatically builds crates' documentation released on
using the nightly release of the Rust compiler.
The current version of the Rust compiler in use is
rustc 1.39.0-nightly (f0b58fcf0 2019-09-11).
If you need a newer version of this compiler, check the
and file a new issue if you don't see an existing request.
The source code of Docs.rs is available on GitHub. If you ever encounter an issue, don't hesitate to report it! (And thanks in advance!)
The README of a crate is taken from the
readme field defined in
Cargo.toml. If a crate doesn't have this field,
no README will be displayed.
Docs.rs is using semver to parse URLs. You can use this feature to access
crates' documentation easily. Example of URL redirections for
|URL||Redirects to documentation of|
|docs.rs/clap||Latest version of clap|
|docs.rs/clap/2.9.3||2.9.3 version (you don't need
You can use badges to show state of your documentation to your users.
The default badge will be pointed at the latest version of a crate.
You can use
version parameter to show status of documentation for
any version you want.
Badge will display in blue if docs.rs is successfully hosting your crate documentation, and red if building documentation failing.
Example badges for mio crate:
|Latest version: https://docs.rs/mio/badge.svg|
|Version 0.4.4: https://docs.rs/mio/badge.svg?version=0.4.4|
|Version 0.1.0: https://docs.rs/mio/badge.svg?version=0.1.0|
You can customize docs.rs builds by defining
[package.metadata.docs.rs] table in your crates' `Cargo.toml`.
An example metadata:
[package] name = "test" [package.metadata.docs.rs] features = [ "feature1", "feature2" ] all-features = true no-default-features = true default-target = "x86_64-unknown-linux-gnu" rustc-args = [ "--example-rustc-arg" ] rustdoc-args = [ "--example-rustdoc-arg" ]
Currently running Docs.rs version is: 0.6.0 (32074e7 2019-09-18)
