Struct PlannedSplit 

#[non_exhaustive]
pub struct PlannedSplit {
    pub spec: SplitSpec,
    pub seed: Option<SplitProgress>,
}

A split as the planner submits it: the spec plus optional seed progress. Seeds are first-writer-wins — a seed never overwrites an existing record — which is the migration path for work that already has a pre-coordination checkpoint. A brand-new source plans without seeds.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

spec: SplitSpec

The split itself.

seed: Option<SplitProgress>

Durable progress to seed if (and only if) the split has none.

Implementations

impl PlannedSplit

pub fn new(spec: SplitSpec) -> PlannedSplit
