Implementations

impl UpdateFeaturesRequest

pub fn get_feature( version: i16, updates: &[FeatureUpdateKey], name: &str, ) -> Result<FeatureUpdateKey>

Java UpdateFeaturesRequest.getFeature.

First matching Feature name (Java FeatureUpdates.find). A missing name is crate::Error::protocol (Java NPE on the null FeatureUpdateKey). v0 rewrites UpgradeType from AllowDowngrade (true is UPGRADE_TYPE_SAFE_DOWNGRADE, false is UPGRADE_TYPE_UPGRADE) and ignores a stored UpgradeType. v1+ is UpgradeType.fromCode on the stored UpgradeType (unknown codes, including Java UNKNOWN 0, become 0) and sets AllowDowngrade from UpgradeType != 1. Encode still writes FeatureUpdates as-is (AllowDowngrade on v0, UpgradeType on v1+).

pub fn feature_updates( version: i16, updates: &[FeatureUpdateKey], ) -> Vec<FeatureUpdateKey>

Java UpdateFeaturesRequest.featureUpdates.

Each FeatureUpdates entry is Self::get_feature of that entry’s name. Duplicate names all become the first match (Java find then FeatureUpdateItem). Empty is empty. Encode still writes FeatureUpdates as-is.
