Struct WindowDescriptor 

pub struct WindowDescriptor {
    pub start_slot: u32,
    pub tenant_id: u32,
    pub opcode: SlotOpcode,
    pub ticket: u32,
    pub required: Vec<Vec<u32>>,
    pub lookahead: Vec<Vec<u32>>,
}

A ticketed window of related slot publications.

Each emitted slot receives a stable prefix of [window_ticket, class_tag] followed by the caller-supplied payload, so wrappers can submit required and lookahead work as one structured batch without hand-assembling the prefix.

Fields

start_slot: u32

Slot index where the first window item should be written.

tenant_id: u32

Tenant id used for all emitted slots.

opcode: SlotOpcode

Slot opcode shared by all emitted slots.

ticket: u32

Stable ticket id correlating every slot in this window.

required: Vec<Vec<u32>>

Required entries for the window.

lookahead: Vec<Vec<u32>>

Lookahead entries for the window.

Implementations

impl WindowDescriptor

pub fn new( start_slot: u32, tenant_id: u32, opcode: SlotOpcode, ticket: u32, required: Vec<Vec<u32>>, lookahead: Vec<Vec<u32>>, ) -> Self

Convenience constructor.

pub fn into_batch(&self) -> BatchDescriptor

Convert the window into a typed batch publication.

pub fn try_into_batch(&self) -> Result<BatchDescriptor, PipelineError>

Convert the window into a typed batch publication with explicit staging and ABI-bound errors.

pub fn publish_into(&self, ring_bytes: &mut [u8]) -> Result<u32, PipelineError>

Publish the full window into the ring and return the number of emitted slots.

Trait Implementations

impl Clone for WindowDescriptor

fn clone(&self) -> WindowDescriptor

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for WindowDescriptor

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

Formats the value using the given formatter.

impl Eq for WindowDescriptor

impl PartialEq for WindowDescriptor

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