Enum rustc_session::session::CtfeBacktrace[−][src]

pub enum CtfeBacktrace {
    Disabled,
    Capture,
    Immediate,
}

Expand description

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

Variants

Disabled

Do nothing special, return the error as usual without a backtrace.

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.
