//!
//! The CrashpadInfo structure is not suitable to expose client options
//! in a generic way at the snapshot level. This structure duplicates
//! option-related fields from the client structure for general use within the
//! snapshot layer and by users of this layer.
//!
//! For objects of this type corresponding to a module, option values are taken
//! from the module’s CrashpadInfo structure directly. If the module has no such
//! such structure, option values appear unset.
//!
//! For objects of this type corresponding to an entire process, option values
//! are taken from the CrashpadInfo structures of modules within the process.
//! The first module found with a set value (enabled or disabled) will provide
//! an option value for the process. Different modules may provide values for
//! different options. If no module in the process sets a value for an option,
//! the option will appear unset for the process. If no module in the process
//! has a CrashpadInfo structure, all option values will appear unset.

  //! values used in the snapshot layer.
