Module potion_contents 

Vanilla PotionContents behavior extension: the methods that need LivingEntity/World, which can’t live alongside the data in steel_registry::data_components::PotionContents.

Functions

apply_potion_contents 🔒

Mirrors vanilla PotionContents.applyToLivingEntity(user, durationScale).

scale_effect_duration 🔒

Mirrors vanilla MobEffectInstance.withScaledDuration: scales duration by scale, leaving the infinite-duration sentinel (-1) and a zero duration untouched, and never rounding a finite result below 1 tick.

to_runtime_instance 🔒

Builds the runtime active-effect state for one registry mob-effect instance, ready to hand to LivingEntity::add_mob_effect.
