# presets

Convenient factories for common compression recipes. Each preset
returns a ready-to-use config that can be further refined by chaining
[`set_module_type()`](coreai_opt.config.CompressionConfig.md#coreai_opt.config.CompressionConfig.set_module_type),
[`set_module_name()`](coreai_opt.config.CompressionConfig.md#coreai_opt.config.CompressionConfig.set_module_name),
[`only_for()`](coreai_opt.config.CompressionConfig.md#coreai_opt.config.CompressionConfig.only_for), or
[`without()`](coreai_opt.config.CompressionConfig.md#coreai_opt.config.CompressionConfig.without).
