Cargo Features

[dependencies]
actix-rt = { version = "2.9.0", default-features = false, features = ["macros", "io-uring"] }
default = macros

The macros feature is set by default whenever actix-rt is added without default-features = false somewhere in the dependency tree.

macros default = actix-macros
io-uring = tokio-uring

Affects system::SystemRunner

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.
