hashbrown = { version = "0.14.3", default-features = false, features = ["nightly", "rustc-internal-api", "rustc-dep-of-std", "raw", "inline-more", "ahash", "rayon", "serde", "rkyv", "allocator-api2", "equivalent"] }- default = ahash, allocator-api2, inline-more
-
These default features are set whenever
hashbrownis added withoutdefault-features = false - nightly rustc-dep-of-std?
-
Enables allocator_api of bumpalo and nightly of optional allocator-api2
Support for allocators that use allocator-api2
- rustc-internal-api rustc-dep-of-std?
- rustc-dep-of-std = alloc, compiler_builtins, core, nightly, rustc-internal-api
- raw
-
Affects
hashbrown::raw… - inline-more default
-
Enables usage of
#[inline]on far more functions than by default in this crate. This may lead to a performance increase but often comes at a compile time cost.
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.
