Expand description

This structure defines the CPU-internal exception vector numbers.

The values are defined by the following manual sections:

  • AMD Volume 2: 8.2
  • Intel Volume 3A: 6.3.1

Variants (Non-exhaustive)§

This enum is marked as non-exhaustive
Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.
