2021-04-26Rust Remove SafeSliceAccess for Arrays, and fix miri. (#6592)Casper2-8/+4
* Fix Miri flag passing and bump Rust version. * Fix Miri problems from Arrays PR. SafeSliceAccess was removed for Arrays. It's kind of unsound. It has two properties: 1. EndianSafe 2. Alignment 1 We only need 1. in create_vector_direct to memcpy data. We both 1. and 2. for accessing things with slices as buffers are built on &[u8] which is unaligned. Conditional compilation implements SafeSliceAccess for >1byte scalars (like f32) on LittleEndian machines which is wrong since they don't satisfy 2. This UB is still accessible for Vectors (though not exercised our tests) as it implements SafeSliceAccess. I'll fix this later by splitting SafeSliceAccess into its 2 properties.

This is a backwards incompatible change but the previous version had UB and was also backwards incompatible so... * Update and test sample rust flatbuffers * Use bitflags crate to properly support rust enums.

2020-01-19[rust] Add use declarations to Rust-generated bindings for imported FB ↵Max Burke4-0/+33
definitions (#5645) * Bugfix for Rust generation of union fields named with language keywords Looking at ParseField, it appears that in the case of unions, an extra field with a `UnionTypeFieldSuffix` is added to the type definition, however, if the name of this field is a keyword in the target language, it isn't escaped. For example, if generating code for rust for a union field named `type`, flatc will generate a (non-keyword escaped) field named `type_type` for this hidden union field, and one (keyword escaped) called `type_` for the actual union contents. When the union accessors are generated, they refer to this `type_type` field, but they will escape it mistakenly, generating code like this: ``` #[inline] #[allow(non_snake_case)] pub fn type__as_int(&self) -> Option<Int<'a>> { if self.type__type() == Type::Int { self.type_().map(|u| Int::init_from_table(u)) } else { None } } ``` Which will fail to build because the field is called `self.type_type()`, not `self.type__type()`. * [Rust] Add crate-relative use statements for FBS includes. At present if a flatbuffer description includes a reference to a type in another file, the generated Rust code needs to be hand-modified to add the appropriate `use` statements. This assumes that the dependencies are built into the same crate, which I think is a reasonable assumption? * Revert "[Rust] Add crate-relative use statements for FBS includes." This reverts commit d554d79fecf5afd6da6fb993b30b4cd523a5889a. * Add updated generated test files. * Fixing Rust test harness to handle new includes. Test binaries need to add references to generated code that's transitively included. This also has the knock-on in that this code (which is referenced by include directives directly in the flatbuffer schema files) also needs to be generated, hence the changes to generate_code.sh. * Test harnesses expect test data to be checked in. Put include_test2 files into the same directory as the include_test2 schema definition. Update all code generation scripts (forgot the batch file from last time). Path updates in Rust test. * Include updated generated code * Address comments raised in PR * Fix failing Rust tests. * Previous merge clobbered this branch change. * Add updated imports to benchmarks. * Clarifying comment per PR request * Update documentation comments per feedback * Remove non-Rust generated files for include tests, per feedback from @rw/@aardappel * Broken code generation batch file * Fix typo * Add TODO for tidying up use declaration traversal sometime in the future * Update test files.

2019-03-08Fix rust crate for big-endian targets (#5229)tymcauley1-64/+84
Thanks for tackling this, @tymcauley ! * big endian docker test -- wip * tweaks * tweaks * tweaks * docker tweaks * fix conditional compilation issues * reactivate other docker tests * try some more cross-platform config (from tymcauley) * Update tests/docker/languages/Dockerfile.testing.rust.big_endian.1_30_1 Co-Authored-By: rw <rw@users.noreply.github.com> * Update tests/docker/languages/Dockerfile.testing.rust.big_endian.1_30_1 Co-Authored-By: rw <rw@users.noreply.github.com> * Update tests/docker/languages/Dockerfile.testing.rust.big_endian.1_30_1 Co-Authored-By: rw <rw@users.noreply.github.com> * 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.

2018-09-02Port FlatBuffers to Rust (#4898)Robert5-0/+3182
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.
