Cargo Features

[dependencies]
halo2-base = { version = "0.4.1", default-features = false, features = ["asm", "halo2-axiom", "display", "profile", "test-utils", "plotters", "jemallocator", "mimalloc"] }

default = display, halo2-axiom, test-utils

These default features are set whenever halo2-base is added without default-features = false somewhere in the dependency tree.

display default

profile

Enables profile of optional halo2-axiom
