Struct HoldingIndex 

pub struct HoldingIndex { /* private fields */ }

A grow-only index of which nodes hold which content ids.

Content never mutates, so a holder fact is monotonic: it is either useful or stale because the holder is unreachable. Merge is set union, giving the index convergence without coordination or consensus. A stale announcement degrades to a peer miss and the fabric continues to any other holder.

Implementations

impl HoldingIndex

pub fn announce(&self, fact: HeldContent) -> Result<()>

Announces that fact.holder holds fact.key.

Re-announcing the same fact is idempotent.

pub fn holders_of(&self, key: &ContentKey) -> Vec<Symbol>

Returns holders announced for key, sorted by symbol order.

pub fn merge(&self, other: &HoldingIndex) -> Result<()>

Merges all facts from other by grow-only set union.

Trait Implementations

impl Default for HoldingIndex

fn default() -> HoldingIndex

Returns the “default value” for a type.
