Improves Rust code generation #8564

csmulhern · 2025-03-22T21:25:18Z

This PR includes the following fixes:

The serialize_human_readable and deserialize_human_readable cfg checks in the flexbuffers crate were using incorrect syntax.

A source file in the flexbuffers crate contained a use statement for an unused class (MapReaderIndexer). This was triggering a compiler warning.

The flatbuffers crate introduces a nightly cfg flag in its build.rs file to conditionally compile code when running a nightly toolchain. Since Rust version 1.79, the cargo:rustc-check-cfg instruction should be used to avoid compiler warnings about unknown cfgs. See: https://blog.rust-lang.org/2024/05/06/check-cfg.html.

The rust_usage_test source code was using deprecated float constants. Constants like EPSILON are now directly on the float primitives (e.g. f32::EPSILON) rather than in the f32 module (std::f32::EPSILON). The new constants have existed since 1.43.0, which is below the MSRV for the flatbuffers crate (1.51).

The Cargo.toml file for the flatbuffers crate was using the package.rust key to define its MSRV (minimum supported Rust version). However, the correct key is package.rust-version.

The Rust code generator produced code with a plethora of warnings. These have been addressed.

Statements such as use core::mem were included at the top of the file, so that the shorthand mem could be used to reference the std::mem module in the generated code. However, not all schemas / configurations would generate code referencing core::mem. This would trigger warnings about unused use statements. These use statements have all been removed, in favor of using the fully qualified name (::core::mem::...) in all generated code.

An exhaustive list of migrated use statements is included below:

alloc::boxed::Box
alloc::string::String
alloc::vec::Vec
core::mem
core::cmp::Ordering

Similarly, use statements were used to bring traits into scope so that the trait methods could be called on types implementing that trait. For example, EndianScalar::to_little_endian. These usages have been converted to UFCS. E.g. x.to_little_endian() -> ::flatbuffers::EndianScalar::to_little_endian(x).

An exhaustive list is of migrated traits is included below:

alloc::string::ToString
flatbuffers::EndianScalar
flatbuffers::Follow

References to externally defined types (e.g. flatbuffers::Vec) have been converted to use absolute paths (e.g. ::flatbuffers::Vec). Using absolute paths provides the most flexibility in terms of how the generated code is used (e.g. include!-ing the generated code in a file that defines a module named flatbuffers would not cause ambiguity around if flatbuffers::Vec references the module or the flatbuffers crate.

Enabling a cfg attribute through cargo::rustc-cfg in build.rs should be coupled with a cargo::rust-check-cfg value so that the compiler knows about the custom cfg. See: https://doc.rust-lang.org/rustc/check-cfg/cargo-specifics.html#cargorustc-check-cfg-for-buildrsbuild-script.

This update fixes a compiler warning from use of the old constants. Constants like EPSILON are now directly on the float primitives (e.g. f32::EPSILON) rather than in the f32 module (std::f32::EPSILON). The new constants have existed since 1.43.0, which appears to be below the MSRV for the flatbuffers crate.

The old code was using package.rust, which triggered a warning about an unused key: warning: flatbuffers/rust/flatbuffers/Cargo.toml: unused manifest key: package.rust The correct key for specifying MSRV is rust-version. See: https://doc.rust-lang.org/cargo/reference/rust-version.html#rust-version.
