Struct DataComponentExactPredicate 

pub struct DataComponentExactPredicate {
    values: Vec<(ComponentEntryRef, ComponentData)>,
}

Exact component values required by a component matcher.

Fields

values: Vec<(ComponentEntryRef, ComponentData)>

Implementations

impl DataComponentExactPredicate

pub const EMPTY: Self

pub fn new(values: Vec<(ComponentEntryRef, ComponentData)>) -> Option<Self>

Creates an exact predicate only when every persistent value can round-trip.

Vanilla’s direct stream codec can admit values rejected by a component’s persistent codec. Steel rejects those here because exact predicates are nested in item components and must not make their containing stack unsavable.

pub fn all_of(components: &DataComponentMap) -> Option<Self>

pub const fn is_empty(&self) -> bool

pub fn values(&self) -> &[(ComponentEntryRef, ComponentData)]

fn from_owned_nbt(tag: &NbtTag) -> Option<Self>

fn to_nbt_value(&self) -> NbtTag
