LatestVersionResolver

xenith_core::conflict

Struct LatestVersionResolver 

Source 
pub struct LatestVersionResolver;
Expand description

Picks the candidate with the highest version field.

If two candidates share the same version the one with the lower chain ID wins, giving a deterministic tie-break.

Trait Implementations§

impl ConflictResolver for LatestVersionResolver

Source§

fn resolve<'life0, 'life1, 'async_trait>( &'life0 self, key: &'life1 StateKey, candidates: Vec<(ChainId, StateValue)>, ) -> Pin<Box<dyn Future<Output = Result<StateValue>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Reduce candidates (one value per chain) to a single resolved StateValue.
