bytemuck has no features set by default.
[dependencies]
bytemuck = { version = "1.18.0", features = ["derive", "extern_crate_alloc", "extern_crate_std", "zeroable_atomics", "align_offset", "min_const_generics", "wasm_simd", "aarch64_simd", "must_cast", "const_zeroed", "unsound_ptr_pod_impl", "latest_stable_rust", "nightly_portable_simd", "nightly_stdsimd", "nightly_float", "nightly_docs"] }
- derive latest_stable_rust? = bytemuck_derive
-
In v2 we'll fix these names to be more "normal".
- extern_crate_alloc extern_crate_std?
-
Affects
bytemuck::allocation
… - extern_crate_std = extern_crate_alloc
- zeroable_maybe_uninit zeroable_atomics latest_stable_rust?
- align_offset latest_stable_rust?
-
All MSRV notes below are GUIDELINES and future versions may require even more MSRV on any feature.
MSRV 1.36: Use
align_offset
method instead of casting tousize
to check alignment of pointers, this may improve codegen in some cases (but it has never been formally benchmarked!) - min_const_generics latest_stable_rust?
-
MSRV 1.51: support arrays via min_const_generics
- wasm_simd latest_stable_rust?
-
MSRV 1.54.0: support wasm simd types
- aarch64_simd latest_stable_rust?
-
MSRV 1.59.0: support aarch64 simd types
- must_cast latest_stable_rust?
-
MSRV 1.64.0: support the
must
module. - const_zeroed latest_stable_rust?
-
MSRV 1.75.0: support const
zeroed()
Affects
bytemuck::zeroed
… - unsound_ptr_pod_impl
-
Do not use if you can avoid it, because this is **unsound**!!!!
- latest_stable_rust = aarch64_simd, align_offset, const_zeroed, derive, min_const_generics, must_cast, wasm_simd, zeroable_atomics, zeroable_maybe_uninit
-
Enables all features that are both sound and supported on the latest stable version of Rust, with the exception of
extern_crate_alloc
andextern_crate_std
. Note: Enabling this feature opts out of any MSRV guarantees! - nightly_portable_simd
-
NOT SEMVER SUPPORTED! TEMPORARY ONLY!
- nightly_stdsimd
- nightly_float
-
Enable
f16
andf128
- nightly_docs
-
Improved documentation using the nightly toolchain
Features from optional dependencies
In crates that don't use the dep:
syntax, optional dependencies automatically become Cargo features. These features may have been created by mistake, and this functionality may be removed in the future.
