impl<T> MultiIndex<T>
Sourcepub fn new(
code: Name,
scope: Name,
table: Name,
indices: &[SecondaryType],
) -> Self
pub fn new( code: Name, scope: Name, table: Name, indices: &[SecondaryType], ) -> Self
Creates a new instance of the MultiIndex struct.
Sourcepub fn store(&self, value: &T, payer: Name) -> Iterator<'_, T>
pub fn store(&self, value: &T, payer: Name) -> Iterator<'_, T>
Stores a given value into the table with a specified payer.
Sourcepub fn find(&self, id: u64) -> Iterator<'_, T>
pub fn find(&self, id: u64) -> Iterator<'_, T>
Searches for a record with a given primary key and returns an iterator.
Sourcepub fn update(&self, iterator: &Iterator<'_, T>, value: &T, payer: Name)
pub fn update(&self, iterator: &Iterator<'_, T>, value: &T, payer: Name)
Updates the record pointed by the given iterator with a new value and payer.
Sourcepub fn remove(&self, iterator: &Iterator<'_, T>)
pub fn remove(&self, iterator: &Iterator<'_, T>)
Removes the record pointed by the given iterator.
Sourcepub fn get(&self, iterator: &Iterator<'_, T>) -> Option<T>
pub fn get(&self, iterator: &Iterator<'_, T>) -> Option<T>
Retrieves the value pointed by the given iterator.
Sourcepub fn get_by_primary(&self, primary: u64) -> Option<T>
pub fn get_by_primary(&self, primary: u64) -> Option<T>
Retrieves the value by its primary key.
Sourcepub fn next(&self, iterator: &Iterator<'_, T>) -> Iterator<'_, T>
pub fn next(&self, iterator: &Iterator<'_, T>) -> Iterator<'_, T>
Returns an iterator pointing to the next record.
Sourcepub fn previous(&self, iterator: &Iterator<'_, T>) -> Iterator<'_, T>
pub fn previous(&self, iterator: &Iterator<'_, T>) -> Iterator<'_, T>
Returns an iterator pointing to the previous record.
Sourcepub fn lower_bound(&self, id: u64) -> Iterator<'_, T>
pub fn lower_bound(&self, id: u64) -> Iterator<'_, T>
Returns an iterator pointing to the first record that is not less than the given primary key.
Sourcepub fn upper_bound(&self, id: u64) -> Iterator<'_, T>
pub fn upper_bound(&self, id: u64) -> Iterator<'_, T>
Returns an iterator pointing to the first record that is greater than the given primary key.
Sourcepub fn get_idx_db(&self, i: usize) -> &dyn IdxTable
pub fn get_idx_db(&self, i: usize) -> &dyn IdxTable
Retrieves a reference to the secondary index database at the given index.
Sourcepub fn idx_update(
&self,
it: &SecondaryIterator,
value: SecondaryValue,
payer: Name,
)
pub fn idx_update( &self, it: &SecondaryIterator, value: SecondaryValue, payer: Name, )
Updates the secondary index with a given iterator, value, and payer.
