Enum ExtendedOpcode

#[repr(u16)]
pub enum ExtendedOpcode {
    Trap = 0,
    Nop = 1,
    GetSp = 2,
}

An extended opcode.

Variants

Trap = 0

Raise a trap.

Nop = 1

Do nothing.

GetSp = 2

Copy the special sp stack pointer register into an x register.

Implementations

impl ExtendedOpcode

pub const MAX: u16 = 2u16

The value of the maximum defined extended opcode.

impl ExtendedOpcode

pub fn new(bytes: u16) -> Option<Self>

Create a new ExtendedOpcode from the given bytes.

Returns None if bytes is not a valid extended opcode.

pub unsafe fn unchecked_new(byte: u16) -> Self

Like new but does not check whether bytes is a valid opcode.

Safety

It is unsafe to pass bytes that is not a valid opcode.

Trait Implementations

impl Clone for ExtendedOpcode

fn clone(&self) -> ExtendedOpcode

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ExtendedOpcode

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

Formats the value using the given formatter.

impl Decode for ExtendedOpcode

Available on crate feature decode only.

fn decode<T>(bytecode: &mut T) -> Result<Self, T::Error>

where T: BytecodeStream,

Decode this type from the given bytecode stream.

impl Hash for ExtendedOpcode

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 ExtendedOpcode

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

This method returns an Ordering between self and other.

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

where Self: Sized,

Compares and returns the maximum of two values.

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

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for ExtendedOpcode

fn eq(&self, other: &ExtendedOpcode) -> 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 PartialOrd for ExtendedOpcode

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

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

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

Tests less than (for self and other) and is used by the < operator.

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

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

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

Tests greater than (for self and other) and is used by the > operator.

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

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