Enum Value 

#[repr(u64)]
pub enum Value {
    EL0t = 0,
    EL1t = 4,
    EL1h = 5,
    EL2t = 8,
    EL2h = 9,
}

AArch64 state (Exception level and selected SP) that an exception was taken from. The possible values are:

M[3:0] | State

0b0000 | EL0t 0b0100 | EL1t 0b0101 | EL1h 0b1000 | EL2t 0b1001 | EL2h

Other values are reserved, and returning to an Exception level that is using AArch64 with a reserved value in this field is treated as an illegal exception return.

The bits in this field are interpreted as follows:

• M[3:2] holds the Exception Level.
• M[1] is unused and is RES 0 for all non-reserved values.
• M[0] is used to select the SP:
  • 0 means the SP is always SP0.
  • 1 means the exception SP is determined by the EL.

Variants

EL0t = 0

EL1t = 4

EL1h = 5

EL2t = 8

EL2h = 9

Trait Implementations

impl Clone for Value

fn clone(&self) -> Value

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl From<Value> for FieldValue<u64, Register>

fn from(v: Value) -> Self

Converts to this type from the input type.

impl PartialEq for Value

fn eq(&self, other: &Value) -> 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 TryFromValue<u64> for Value

type EnumType = Value

fn try_from_value(v: u64) -> Option<Self::EnumType>

impl Copy for Value

impl Eq for Value

impl StructuralPartialEq for Value
