pub struct Flag(/* private fields */);Expand description
A boolean parameter value used for module-owned control state.
Param<Flag> gives the value an identity in the module tree, allowing parameter groups to
select it by id or path just like other module-owned values. The field holding the flag gives
it its meaning; for example, Dropout::training uses an enabled flag to permit stochastic
behavior on an autodiff device.
§Records
Flags are runtime configuration, not persisted model state. Module records omit their value,
lifecycle state and ParamId; loading a record preserves the destination module’s flag
exactly as configured. This mirrors tensor parameters, whose values and ids are recorded but
whose require_grad configuration comes from the destination module.
§Devices
Flags are host-side control state and do not reside on a compute device. Moving or forking a
module preserves a flag unchanged, and flags do not contribute entries to Module::devices.
