Cargo Features

[dependencies]
libseat = { version = "0.2.1", default-features = false, features = ["custom_logger"] }
default = custom_logger

The custom_logger feature is set by default whenever libseat is added without default-features = false somewhere in the dependency tree.

custom_logger default = cc, pkg-config

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.

cc build custom_logger
pkg-config build custom_logger
