Cargo Features

[dependencies]
umbra-lang = { version = "0.21.0", default-features = false, features = ["env_logger", "jemallocator", "redox_liner"] }
default = env_logger, jemallocator, redox_liner

These default features are set whenever umbra-lang 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.

env_logger default

Enables env_logger ^0.8

jemallocator not msvc default
