-// FixedBuffer provides a simple way to allocate objects within a fixed chunk
-// of memory. Objects are allocated by calling the |Allocate| method, which
-// extends the buffer accordingly. Objects allocated in this way are not freed
-// explicitly. Instead, they remain valid so long as the FixedBuffer remains
-// valid. The Leak method may be used to steal the underlying memory from the
-// FixedBuffer.
-//
-// Typical usage:
-//
-// {
-// FixedBuffer buf(8 + 8);
-//
-// int* a = static_cast<int*>(buf->Allocate(sizeof(int)));
-// *a = 2;
-//
-// double* b = static_cast<double*>(buf->Allocate(sizeof(double)));
-// *b = 3.14f;
-//
-// void* data = buf.Leak();
-// Process(data);
-//
-// free(data);
