Struct PartitionSpec 

pub struct PartitionSpec {
    pub chunking: Chunking,
    pub window: Option<(Bound, Bound)>,
    pub order: PartitionOrder,
}

A parsed partition spec:

spec   := chunking [ "in" window ] [ order ]
window := Form 1 range (e.g. `25%..75%`)
order  := unchanged | smallest_first | largest_first | random

The window scopes the chunking: the chunking resolves against the window’s ordinal range instead of the full extent, so percentages inside the chunking are relative to the window. Without a window, the chunking spans the whole extent. The order keyword reorders the resolved list for iteration; partition idx keeps identifying the generation position.

Fields

chunking: Chunking

The shape that carves the (windowed) domain.

window: Option<(Bound, Bound)>

Optional in start..end window the chunking applies to.

order: PartitionOrder

Iteration order of the resolved list.

Implementations

impl PartitionSpec

pub fn single_range(start: Bound, end: Bound) -> Self

A windowless, unordered Form 1 spec.

pub fn delta_list(deltas: Vec<Bound>) -> Self

A windowless, unordered Form 2/3 spec.

Trait Implementations

impl Clone for PartitionSpec

fn clone(&self) -> PartitionSpec

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PartitionSpec

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

Formats the value using the given formatter.

impl PartialEq for PartitionSpec

fn eq(&self, other: &PartitionSpec) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.

impl ReflectedValue for PartitionSpec

fn type_name(&self) -> &str

Type name for diagnostics and describe output.

fn display(&self) -> String

Human-readable string representation. Used by stdout adapter, logging, and diagnostics.

fn to_json_value(&self) -> Value

JSON representation for serialization and HTTP bodies.

fn as_any(&self) -> &dyn Any

Downcast to the concrete type. Only works when the consuming code has the concrete type in scope (same crate or shared dep).

fn clone_reflected(&self) -> Box<dyn ReflectedValue>

Clone into a new boxed trait object.

fn try_as_str(&self) -> Option<String>

Try to represent as a string. Many types have a canonical string form (UUIDs, timestamps, IP addresses).

fn try_as_u64(&self) -> Option<u64>

Try to represent as u64.

fn try_as_f64(&self) -> Option<f64>

Try to represent as f64.

fn try_as_bytes(&self) -> Option<&[u8]>

Try to represent as bytes.
