Enum ConcurrencyClass 

pub enum ConcurrencyClass {
    Stateless,
    OrderedStateful,
    FrameGroupSerial {
        group_size: usize,
        max_active_groups: Option<usize>,
    },
    Source,
}

Declares how scheduler may run node callbacks across frames.

Variants

Stateless

Callback has no cross-frame mutable state.

OrderedStateful

Callback may prepare out of order but must commit in increasing frame order.

FrameGroupSerial

Callback serializes frames that share the same fixed-size output group.

Fields

group_size: usize

Number of output frames per scheduler group. Zero is treated as one.

max_active_groups: Option<usize>

Maximum distinct output groups active at once. None allows unbounded speculation.

Source

Callback is a source and may declare source-specific capability limits.

Implementations

impl ConcurrencyClass

pub const fn frame_group_serial(group_size: usize) -> ConcurrencyClass

Creates a concurrency class that serializes frames in fixed-size output groups.

pub const fn frame_group_serial_unbounded(group_size: usize) -> ConcurrencyClass

Creates grouped serial scheduling without bounding distinct active groups.

pub const fn group_size(self) -> Option<usize>

Returns output group size for grouped serial scheduling.

pub const fn as_str(self) -> &'static str

Returns stable diagnostic name.

Trait Implementations

impl Clone for ConcurrencyClass

fn clone(&self) -> ConcurrencyClass

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ConcurrencyClass

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

Formats the value using the given formatter.

impl PartialEq for ConcurrencyClass

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