// nor converted. This means that native handlers are not guaranteed to work and
// cannot modify the request data. Request properties, such as headers, can still
// be modified.
// Prefer implementing a Goyave handler.

// This feature is a compatibility layer with the rest of the Golang web ecosystem.
// Prefer using Goyave handlers if possible.
