Cargo Features

[dependencies]
witchcraft-server = { version = "3.11.0", default-features = false, features = ["jemalloc"] }
default = jemalloc

The jemalloc feature is set by default whenever witchcraft-server is added without default-features = false somewhere in the dependency tree.

jemalloc default = tikv-jemalloc-ctl, tikv-jemallocator

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.

tikv-jemalloc-ctl jemalloc
tikv-jemallocator jemalloc
