11untrusted.rs
12============
13
14Safe, fast, zero-panic, zero-crashing, zero-allocation parsing of untrusted
15inputs in Rust.
16
17untrusted.rs is 100% Rust with no use of `unsafe`. It never uses the heap.
18No part of untrusted.rs's API will ever panic or cause a crash. It is
19`#![no_std]` and so it works perfectly with both libcore- and libstd- based
20projects. It does not depend on any crates other than libcore.
21
22untrusted.rs is intended to be used with the latest version of Rust Stable.
23It should usually work with the latest Rust Beta and Rust Nightly versions
24too. Using a version of untrusted.rs other than the latest release available
25on crates.io is not recommended.

29Documentation
30-------------
31
32See the documentation at
33https://briansmith.org/rustdoc/untrusted/.
34
35To use untrusted.rs in your project, add a dependency to your
36Cargo.toml like this:
37
38```
39[dependencies]
40untrusted = "0.2"
41```

45Examples
46--------
47
48[*ring*](https://github.com/briansmith/ring)'s parser for the subset of ASN.1
49DER it needs to understand,
50[`ring::der`](https://github.com/briansmith/ring/blob/master/src/der.rs), is
51built on top of untrusted.rs. *ring* also uses untrusted.rs to parse ECC public
52keys, RSA PKCS#1 1.5 padding, and everything else.
53
54All of [webpki](https://github.com/briansmith/webpki)'s parsing of X.509
55certificates (also ASN.1 DER) is done using untrusted.rs.

74Currently, the biggest needs for this library are:
75
76* Unit tests.
77* Documentation.
78* More examples.
79* Static analysis and fuzzing.

83Online Automated Testing
84------------------------
85
86Travis CI is used for Android, Linux, and Mac OS X. The tests are run for the
87current release of each Rust channel (Stable, Beta, Nightly). Since
88untrusted.rs only depends on libcore and it only uses 100% cross-platform code
89without using `unsafe`, it should work anywhere as long as these platforms are
90passing.
