    Exception(Exception),
}

Represents the cause of a trap, based on the value of the mcause register.

Variants

The trap was an interrupt.

Exception(Exception)

The trap was an exception.

Implementations

impl Trap

pub fn from_mcause() -> Result<Self, InvalidMcause>

Reads the value of the mcause register and interprets it as a Trap.

Returns

• Ok(Trap) if the value of the mcause register is a valid trap code
• Err(InvalidMcause) if the value of the mcause register is not a valid trap code. Note that this Should Not Happen if the hardware is functioning correctly.

fn from_bits(bits: usize) -> Result<Self, InvalidMcause>

Trait Implementations

impl Clone for Trap

fn clone(&self) -> Trap

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Trap

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

Formats the value using the given formatter.

impl Display for Trap

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

Formats the value using the given formatter.

impl PartialEq for Trap

fn eq(&self, other: &Trap) -> 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.
