Struct SplitDecision 

pub struct SplitDecision {
    pub should_split: bool,
    pub unsplit_cost: u32,
    pub split_cost: u32,
    pub children: Vec<PartitionDecision>,
}

Split decision result for recursive partitioning.

Fields

should_split: bool

Should we split this block?

unsplit_cost: u32

Cost of the unsplit block.

split_cost: u32

Cost of the split blocks (sum).

children: Vec<PartitionDecision>

Child decisions (if split).

Implementations

impl SplitDecision

pub const fn new() -> Self

Creates a new split decision.

pub const fn no_split(cost: u32) -> Self

Creates a decision to not split.

pub fn split( unsplit_cost: u32, split_cost: u32, children: Vec<PartitionDecision>, ) -> Self

Creates a decision to split.
