Expand description

The behavior of the CTFE engine when an error occurs with regards to backtraces.

Variants

Disabled

Capture

Capture a backtrace at the point the error is created and return it in the error (to be printed later if/when the error ever actually gets shown to the user).

Immediate

Capture a backtrace at the point the error is created and immediately print it out.
