Struct indexical::IndexedDomain
source · pub struct IndexedDomain<T: IndexedValue> { /* private fields */ }
Expand description
An indexed collection of objects.
Contains a reverse-mapping from T
to T::Index
for efficient lookups of indices.
Implementations§
source§impl<T: IndexedValue> IndexedDomain<T>
impl<T: IndexedValue> IndexedDomain<T>
sourcepub fn new(domain: IndexVec<T::Index, T>) -> Self
pub fn new(domain: IndexVec<T::Index, T>) -> Self
Creates a new domain from an indexed vector.
Consider using the FromIterator
implementation if you don’t want to manually construct
an IndexVec
object.
sourcepub fn value(&self, index: T::Index) -> &T
pub fn value(&self, index: T::Index) -> &T
Gets the object corresponding to index
.
Panics if index
is not within the domain.
sourcepub fn index(&self, value: &T) -> T::Index
pub fn index(&self, value: &T) -> T::Index
Gets the index corresponding to value
.
Panics if value
is not within the domain.
sourcepub fn insert(&mut self, value: T) -> T::Index
pub fn insert(&mut self, value: T) -> T::Index
Adds value
to the domain, returning its new index.
sourcepub fn as_vec(&self) -> &IndexVec<T::Index, T>
pub fn as_vec(&self) -> &IndexVec<T::Index, T>
Returns immutable access to the underlying indexed vector.
sourcepub fn ensure(&mut self, value: &T) -> T::Index
pub fn ensure(&mut self, value: &T) -> T::Index
Similar to IndexedDomain::index
, except it adds value
to the domain if it does not exist yet.
sourcepub fn iter(&self) -> impl Iterator<Item = &T> + '_
pub fn iter(&self) -> impl Iterator<Item = &T> + '_
Returns an iterator over all elements of the domain.
sourcepub fn indices(&self) -> impl Iterator<Item = T::Index>
pub fn indices(&self) -> impl Iterator<Item = T::Index>
Returns an iterator over all indices of the domain.
sourcepub fn iter_enumerated(&self) -> impl Iterator<Item = (T::Index, &T)> + '_
pub fn iter_enumerated(&self) -> impl Iterator<Item = (T::Index, &T)> + '_
Returns an iterator over all pairs of indices and elements of the domain.
