RISC-V interrupt causes.

If the interrupt bit (the highest bit) in the mcause register is 1, the rest of the mcause register is interpreted as an interrupt cause.

See “3.1.20 Machine Cause Register (mcause)” in RISC-V Privileged Architectures, v1.10.

Trait Implementations

impl Clone for Interrupt

fn clone(&self) -> Interrupt

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Interrupt

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

Formats the value using the given formatter.

impl Display for Interrupt

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

Formats the value using the given formatter.

impl LowerHex for Interrupt

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

Formats the value using the given formatter.

impl PartialEq for Interrupt

fn eq(&self, other: &Interrupt) -> 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<usize> for Interrupt

type Error = &'static str

The type returned in the event of a conversion error.

fn try_from(value: usize) -> Result<Self, Self::Error>

Performs the conversion.

impl UpperHex for Interrupt

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

Formats the value using the given formatter.

impl Copy for Interrupt

impl Eq for Interrupt

impl StructuralPartialEq for Interrupt
