Use Sized trait for Self, to remove this kind of warning:

Because it would be a hard error in the next Rust version.

This will probably be an ongoing issue seeing how Rust changes all the time. Currently doesn't work with nightly rustc 1.0.0-nightly (c5961ad06 2015-01-28 21:49:38 +0000).

Fixed somewhat in #4 but needs more work (cargo test in particular).

at rustc 1.0.0-nightly (c5961ad06 2015-01-28 21:49:38 +0000)

Renamed std::io to std::old_io since io is moving somewhere. Added a couple of missing new trait requirements.

cargo test is still failing:

copy_memory is already deprecated, as per rust-lang/rust#27740 and removed from Rust 1.5

After applying #14 and this PR, suruga can be built and passes cargo test on Rust 1.5

It won't compile in Rust 1.5 without the UFC

(Actually it still won't compile in Rust 1.5 because of a different error. The error is the use of deprecated std::slice::bytes::copy_memory in src/client.rs:4. See #15)

This patchset fixes:

• obsolete syntax issues
• crypto algorithms due to overflow semantic changes
• std::io changes

rustc version: nightly 30e1f9a1c 2015-03-14

WIP of #2. not intended to merge yet.

der todos:

• from_tlv refactor
• reduce clone: slices rather than owning vectors
• re-re-review chrono routine (datetime depends on it, so cert validation may rely on it)

x509 todos:

• prepare proper testsuite (currently using nist pkix. use other suites too), test integration
• more validation impl & test
• rsa.. boring

Yes, the most dangerous code in the world! I currently only implemented DER parser a bit. I have to implement ASN.1 tree -> certificate parser and certificate validator. Not sure how macros work well for this..
