default = all_components, config_parsing, yaml_format

These default features are set whenever log4rs 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.

log-mdc json_encoder? pattern_encoder?

serde config_parsing json_encoder?

thread-id json_encoder? pattern_encoder?

Enables thread-id ^4
