Struct tartan_arch::aarch64::interrupt::Class

#[repr(transparent)]
pub struct Class(_);

Available on AArch64 only.

Classifies different exception causes.

Note that the Arm documentation defines more variants than are defined in this type. This only includes exception classes that can be triggered from Aarch64 state and taken to EL1.

Implementations

impl Class

pub const Wait: Self = _

Trapped execution of a wait instruction (WFE/WFI).

pub const FPUAccess: Self = _

Trapped access to a FPU/vector register or instruction.

pub const IllegalState: Self = _

Tried to execute instructions after an illegal return.

pub const SupervisorCall: Self = _

Triggered a system call via the SVC instruction.

pub const SystemInstruction: Self = _

Trapped access to a system register or instruction.

pub const VectorAccess: Self = _

Trapped access to a vector register or instruction.

Instruction abort triggered at current exception level.

pub const PCAlignment: Self = _

Program counter not properly aligned.

pub const DataAbortFromLower: Self = _

Data abort triggered at lower exception level.

pub const DataAbortFromCurrent: Self = _

Data abort triggered at current exception level.

pub const SPAlignment: Self = _

Stack pointer not properly aligned.

pub const FloatException: Self = _

Trapped floating point exception.

pub const SystemError: Self = _

System error (SError).

pub const BreakpointFromLower: Self = _

Breakpoint triggered at lower exception level.

pub const BreakpointFromCurrent: Self = _

Breakpoint triggered at current exception level.

pub const StepFromLower: Self = _

Software step at lower exception level.

pub const StepFromCurrent: Self = _

Software step at current exception level.

pub const WatchpointFromLower: Self = _

Watchpoint triggered at lower exception level.

pub const WatchpointFromCurrent: Self = _

Watchpoint triggered at current exception level.

pub const BreakpointInstruction: Self = _

Executed a BRK breakpoint instruction.

pub const fn name(self) -> Option<&'static str>

The name of the enum variant in code, if one is defined for this value.

An identical method is available through the CEnum trait, but this version is declared const (which is currently unstable on traits).

Trait Implementations

impl CEnum<u8> for Class

fn name(self) -> Option<&'static str>

The name of the enum variant in code, if one is defined for this value.

impl Clone for Class

fn clone(&self) -> Class

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Class

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

Formats the value using the given formatter.

impl Default for Class

fn default() -> Class

Returns the “default value” for a type.

impl From<Class> for u8

fn from(enum_value: Class) -> Self

Converts to this type from the input type.

impl From<u8> for Class

fn from(repr: u8) -> Self

Converts to this type from the input type.

impl Hash for Class

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)where
    H: Hasher,
    Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for Class

fn cmp(&self, other: &Class) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Selfwhere
    Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Selfwhere
    Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere
    Self: Sized + PartialOrd<Self>,

Restrict a value to a certain interval.

impl PartialEq<Class> for Class

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl PartialOrd<Class> for Class

fn partial_cmp(&self, other: &Class) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

This method tests less than (for self and other) and is used by the < operator.

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

This method tests less than or equal to (for self and other) and is used by the <= operator.

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

This method tests greater than (for self and other) and is used by the > operator.

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

This method tests greater than or equal to (for self and other) and is used by the >= operator.
