// Each "class" of certificate error/warning has its own unique ID. This is
// essentially like an error code, however the value is not stable. Under the
// hood these IDs are pointers and use the process's address space to ensure
// uniqueness.
//
// Equality of CertErrorId can be done using the == operator.
//
// To define new error IDs use the macro DEFINE_CERT_ERROR_ID().
CertErrorId;

// DEFINE_CERT_ERROR_ID() creates a CertErrorId given a non-null C-string
// literal. The string should be a textual name for the error which will appear
// when pretty-printing errors for debugging. It should be ASCII.
//
// TODO(crbug.com/634443): Implement this -- add magic to ensure that storage
//                         of identical strings isn't pool.

// Returns a debug string for a CertErrorId. In practice this returns the
