Cargo Features

[dependencies]
seize = { version = "0.4.9", default-features = false, features = ["fast-barrier"] }
default = fast-barrier

The fast-barrier feature is set by default whenever seize is added without default-features = false somewhere in the dependency tree.

fast-barrier default = libc, windows-sys

Enables runtime detection of fast memory barriers on Linux and Windows.

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.

libc fast-barrier
windows-sys win fast-barrier

Enables windows-sys ^0.52
