Struct IndexedConstraint 

Source 
pub struct IndexedConstraint<K = IndexKey> { /* private fields */ }
Expand description

Owned handle returned by an indexed single-relation constraint! declaration.

IDs refer to rows of the originating model. get supports integer, string, and tuple keys, including sparse domains.

Implementations§

Source§

impl<K> IndexedConstraint<K>

Source

pub fn len(&self) -> usize

Number of domain entries (not the number of lowered rows).

Source

pub fn is_empty(&self) -> bool

Source

pub fn get<Q: Into<IndexKey>>(&self, key: Q) -> Option<ConstraintHandle>

Look up an entry, returning None for missing or filtered-out keys.

Source§

impl<K: FromIndexKey> IndexedConstraint<K>

Source

pub fn iter(&self) -> impl Iterator<Item = (K, ConstraintHandle)> + '_

Iterate typed keys and copied IDs in the original domain order.
