All uses of `unsafe` are now thoroughly documented with arguments and
informal proofs of correctness as well as conditions that must hold for
these arguments to pass.
This commit also reduces the number of `unsafe` uses by 7, bringing the
count to ~10 non-test uses of `unsafe`.
The directory structure has changed to better isolate crates serving
core and contrib. The new directory structure is:
contrib/
lib/ - the contrib library
core/
lib/ - the core Rocket library
codegen/ - the "compile extension" codegen library
codegen_next/ - the new proc-macro library
examples/ - unchanged
scripts/ - unchanged
site/ - unchanged
This commit also removes the following files:
appveyor.yml - AppVeyor (Rust on Windows) is far too spotty for use
rustfmt.toml - rustfmt is, unfortunately, not mature enough for use
Finally, all example Cargo crates were marked with 'publish = false'.
On Travis, fetching file creation time fails. Because codegen tests
depended on being able to retrieve this time, the tests themselves would
fail. Instead of failing outright, this commit makes an effort to find
_some_ time to associate with a file's creation, even if the time is
suboptimal.
In this commit, Rocket's codegen tests now search for the correct
library to depend on, independent of compiletest. This solution should
be robust against platform differences.
These changes allow any type that implements `FnOnce`, instead of `Fn`,
to be used as attach or launch fairings via `AdHoc`. Furthermore, the
`Sync` bound was also lifted.
Resolves#522.
The 'codegen_next' crate will eventually be renamed 'codegen'. It
contains procedural macros written with the upcoming 'proc_macro' APIs,
which will eventually be stabilized. All compiler extensions in the
present 'codegen' crate will be rewritten as procedural macros and moved
to the 'codegen_next' crate.
At present, macros from 'codegen_next' are exported from the core
`rocket` crate automatically. In the future, we may wish to feature-gate
this export to allow using Rocket's core without codegen.
Resolves#16.
