* Fixes checks for serde features in flexbuffers crate * Removes unused MapReaderIndexer use statement * Fixes warning about nightly cfg usage 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. * Migrates usage of deprecated float constants 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. * Fixes incorrect key in flatbuffers Cargo.toml 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. --------- Co-authored-by: Wouter van Oortmerssen <aardappel@gmail.com>
