Enum Cop0Op 

pub enum Cop0Op {
    Mfc0,
    Dmfc0,
    Mtc0,
    Dmtc0,
}

The COP0 access forms, decoded from the rs field of a COP0 instruction.

Split out so the decoder names them rather than the executor re-deriving them from raw bits.

Variants

Mfc0

MFC0 rt, rd — 32-bit read, sign-extended.

Dmfc0

DMFC0 rt, rd — 64-bit read.

Mtc0

MTC0 rt, rd — 32-bit write.

Dmtc0

DMTC0 rt, rd — 64-bit write.

Implementations

impl Cop0Op

pub const fn from_rs(rs: u8) -> Option<Self>

Decode the rs field of a COP0 instruction, if it names an access form.

Returns None for the TLB and ERET encodings (rs bit 4 set), which are separate instructions handled by T-12-002 and T-12-004.

Trait Implementations

impl Clone for Cop0Op

fn clone(&self) -> Cop0Op

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Cop0Op

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Cop0Op

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Cop0Op

fn eq(&self, other: &Cop0Op) -> 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 Serialize for Cop0Op

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for Cop0Op

impl Eq for Cop0Op

impl StructuralPartialEq for Cop0Op
