Cargo Features
[dependencies]
ahash = { version = "0.8.6", default-features = false, features = ["std", "runtime-rng", "compile-time-rng", "no-rng", "atomic-polyfill", "serde"] }
- default = runtime-rng, std
-
These default features are set whenever
ahash
is added without
somewhere in the dependency tree.default-features = false - std default
-
Enabling this will enable
AHashMap
andAHashSet
.Affects

… - runtime-rng default = getrandom
-
Runtime random key generation using getrandom.
- compile-time-rng = const-random
-
This is an alternative to runtime key generation which does compile time key generation if runtime-rng is not available.
(If runtime-rng is enabled this does nothing.)
If this is on (and runtime-rng is off) it implies the produced binary will not be identical.
If this is disabled and runtime-rng is unavailable constant keys are used. - no-rng
-
Do not use any random number generator (either at compile time or runtime)
If either runtime-rng or compile-time-rng are enabled this does nothing. - atomic-polyfill
-
in case this is being used on an architecture lacking core::sync::atomic::AtomicUsize and friends
Enables atomic-polyfill, atomic-polyfill of once_cell
Features from optional dependencies
In crates that don't use the dep:
syntax, optional dependencies automatically become Cargo features.
- const-random compile-time-rng?
- serde implicit feature
- getrandom runtime-rng
