Enum CellSelection 

pub enum CellSelection {
    SingleSource {
        source: usize,
    },
    Precedence {
        source: usize,
        members: Vec<usize>,
    },
    Combined {
        rule: MergeCombine,
        members: Vec<usize>,
    },
}

How the merge arrived at the value it wrote for one channel of one cell.

The distinction between CellSelection::Precedence and CellSelection::Combined is load-bearing rather than cosmetic: under MergeCombine::Mean or MergeCombine::Median - and Mean is the default - the emitted value is a combination of the agreeing members, so “which contributor supplied this cell” has no answer. The honest record there is the member set and the rule that combined them, and this type refuses to pretend otherwise.

Variants

SingleSource

One source carried the cell; it was carried through as gap fill. Also recorded in MergeReport::single_source.

Fields

source: usize

Index into the input slice.

Precedence

Precedence picked one source out of an agreeing set.

Fields

source: usize

Index into the input slice of the source whose value was written.

members: Vec<usize>

Every source in the accepted consensus, ascending.

Combined

The written value is a combination of the members; no single source supplied it.

Fields

rule: MergeCombine

The rule that produced the written value.

members: Vec<usize>

Every source in the accepted consensus, ascending.

Implementations

impl CellSelection

pub fn selected_source(&self) -> Option<usize>

The single source whose value was written, when one exists.

None for CellSelection::Combined, where no single contributor supplied the value.

pub fn members(&self) -> Vec<usize>

Every source in the accepted consensus.
