Cargo Features

[dependencies]
snmalloc-sys = { version = "0.3.5", default-features = false, features = ["build_cc", "build_cmake", "native-cpu", "check", "notls"] }
default = build_cmake

The build_cmake feature is set by default whenever snmalloc-sys is added without default-features = false somewhere in the dependency tree.

build_cc = cc
build_cmake default = cmake
qemu debug android-lld native-cpu
local_dynamic_tls win8compat usecxx17 check
lto notls

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.

cc build build_cc?
cmake build build_cmake
