Cargo Features

[dependencies]
ckb-std = { version = "0.15.3", default-features = false, features = ["calc-hash", "allocator", "simulator", "dlopen-c", "build-with-clang", "libc", "ckb2023"] }

default = allocator, calc-hash, ckb-types, libc

These default features are set whenever ckb-std is added without default-features = false somewhere in the dependency tree.

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.
