* Resolved Rust warnings during big-endian builds.
* Unify Rust test suites for x86 and MIPS builds.
Note that I had to add four extra packages to the MIPS `Dockerfile`:
`libexpat1`, `libmagic1`, `libmpdec2`, and `libreadline7`. For a reason
I couldn't identify, even the simplest Rust MIPS binaries run with
`qemu-mips` would fail with a segfault when run through this
`Dockerfile`. After installing the `gdb-multiarch` package to attempt to
debug the issue, the binaries ran successfully. I pared down the
packages installed by `gdb-multiarch`, and these four packages are the
minimum subset necessary to get Rust MIPS binaries running under
`qemu-mips`.
* Changed Rust tests to use `Vector`s instead of direct-slice-access.
The direct-slice-access method is not available on big-endian targets,
but `flatbuffers::Vector`s provide an array interface that is available
on all platforms.
* Resolved FooStruct endianness issues using explicit struct constructor.
This more closely resembles how FlatBuffers structs are constructed in
generated Rust code.
* Added explanation of how `FooStruct` parallels generated struct code.
Also collected duplicate implementations of `FooStruct` into a common
location.
This runs a script in TravisCI that executes a bunch of small Docker image
scripts to test the language ports in isolated environments. This allows us to
test multiple language versions with little additional complexity.
Covers:
+ Java OpenJDK 10.0.2
+ Java OpenJDK 11.0.1
+ Node 10.13.0
+ Node 11.2.0
+ Python CPython 2.7.15
+ Python CPython 3.7.1
+ Rust 1.30.1
With the old-style code, the test fails with a borrow-checker error:
```
#[inline]
pub fn name(&'a self) -> &'a str {
self._tab.get::<flatbuffers::ForwardsUOffset<&str>>(Monster::VT_NAME, None).unwrap()
}
```
```
error[E0597]: `e` does not live long enough

```
* Fixed MakeCamelCase behavior when supplied Upper_Camel_Case,
snake_case and UPPERCASE strings.
* Modified the rust integration test to reflect changes.
This is a port of FlatBuffers to Rust. It provides code generation and a
runtime library derived from the C++ implementation. It utilizes the
Rust type system to provide safe and fast traversal of FlatBuffers data.
There are 188 tests, including many fuzz tests of roundtrips for various
serialization scenarios. Initial benchmarks indicate that the canonical
example payload can be written in ~700ns, and traversed in ~100ns.
Rustaceans may be interested in the Follow, Push, and SafeSliceAccess
traits. These traits lift traversals, reads, writes, and slice accesses
into the type system, providing abstraction with no runtime penalty.
