Enum Stage 

pub enum Stage {
    Ic,
    Rf,
    Ex,
    Dc,
    Wb,
}

The five pipeline stages, in hardware order (UM §4.1, Figure 4-1).

Note the names: IC and DC, not IF/DF. The manual’s whole interlock and exception taxonomy is stated stage-relative, so these spellings are what make a citation resolvable.

Variants

Ic

Instruction Cache fetch.

Rf

Register Fetch.

Ex

Execution.

Dc

Data Cache fetch — the bus access, and where interrupts are sampled.

Wb

Write Back.

Trait Implementations

impl Clone for Stage

fn clone(&self) -> Stage

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Stage

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Stage

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for Stage

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 PartialEq for Stage

fn eq(&self, other: &Stage) -> 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 Stage

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 Stage

impl Eq for Stage

impl StructuralPartialEq for Stage
