Check biome tags

Use the world's live biome tags without loading chunks:

use mod_api::{Host, LevelRef};

fn is_forest(host: &dyn Host, level: LevelRef, biome: &str) -> Option<bool> {
    host.level_biome_in_tag(level, biome, "minecraft:is_forest")
}

The tag may also start with #. An undefined tag returns Some(false) for a known biome. An unknown biome or unavailable level returns None; do not confuse that with a known biome outside the tag. Data-pack biome tags participate in this query.
