Enum ScopfDeviceClassLayout 

#[non_exhaustive]
pub enum ScopfDeviceClassLayout {
    Contiguous {
        producers_first: bool,
    },
    Interleaved,
}

How the two device classes sit in the simple_dispatchable_device section.

A model that stacks producers and consumers into one variable vector addresses a device by a per class offset, which is a bijection only when each class owns one unbroken run. Reading the order without that precondition is the one mistake this type makes unavailable.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Contiguous

Each class is one unbroken run. producers_first says which run starts first.

Fields

producers_first: bool

Interleaved

The two classes interleave, so no per class offset addresses a device.

Implementations

impl ScopfDeviceClassLayout

pub fn producers_first(self) -> Option<bool>

Whether the producer run starts before the consumer run, or None when the classes interleave and no offset scheme holds.

Trait Implementations

impl Clone for ScopfDeviceClassLayout

fn clone(&self) -> ScopfDeviceClassLayout

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ScopfDeviceClassLayout

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ScopfDeviceClassLayout

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for ScopfDeviceClassLayout

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
