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)

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.

Trait Implementations

impl Clone for ExceptionVector

fn clone(&self) -> ExceptionVector

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ExceptionVector

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for ExceptionVector

fn eq(&self, other: &ExceptionVector) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl TryFrom<u8> for ExceptionVector

fn try_from(exception_vector_number: u8) -> Result<Self, Self::Error>

Tries to convert the exception vector number to ExceptionVector

Fails if exception vector number is Coprocessor Segment Overrun, reserved or not exception vector number

type Error = InvalidExceptionVectorNumber

The type returned in the event of a conversion error.

impl Copy for ExceptionVector

impl StructuralPartialEq for ExceptionVector
