Cargo Features

crossbeam-skiplist_piedb = { version = "0.8.11", default-features = false, features = ["std", "alloc"] }
default = std

The std feature is set by default whenever crossbeam-skiplist_piedb is added without default-features = false somewhere in the dependency tree.

std default = alloc

Enable to use APIs that require std. This is enabled by default.

Enables std of crossbeam-epoch and crossbeam-utils

alloc std

Enable to use APIs that require alloc. This is enabled by default and also enabled if the std feature is enabled.

NOTE: Disabling both std and alloc features is not supported yet.

Enables alloc of crossbeam-epoch

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.
