Struct FallbackWSetBuilder 

pub struct FallbackWSetBuilder<K, R>
where
    K: DataTrait + ?Sized,
    R: WeightTrait + ?Sized,
{ /* private fields */ }

A builder for batches from ordered update tuples.

Trait Implementations

impl<K, R> Builder<FallbackWSet<K, R>> for FallbackWSetBuilder<K, R>

where Self: SizeOf, K: DataTrait + ?Sized, R: WeightTrait + ?Sized,

fn with_capacity( factories: &FallbackWSetFactories<K, R>, key_capacity: usize, _value_capacity: usize, ) -> Self

Creates an empty builder with estimated capacities for keys and key-value pairs. Only tuple_capacity >= key_capacity makes sense but implementations must tolerate contradictory capacity requests.

fn for_merge<'a, B, I>( factories: &FallbackWSetFactories<K, R>, batches: I, location: Option<BatchLocation>, ) -> Self

where B: BatchReader, I: IntoIterator<Item = &'a B> + Clone,

Creates an empty builder to hold the result of merging batches. Optionally, location can specify the preferred location for the result of the merge.

fn push_time_diff(&mut self, time: &(), weight: &R)

Adds time-diff pair (time, weight).

fn push_val(&mut self, val: &DynUnit)

Adds value val.

fn push_key(&mut self, key: &K)

Adds key key.

fn push_time_diff_mut(&mut self, time: &mut (), weight: &mut R)

Adds time-diff pair (time, weight).

fn push_val_mut(&mut self, val: &mut DynUnit)

Adds value val.

fn push_key_mut(&mut self, key: &mut K)

Adds key key.

fn push_val_diff(&mut self, val: &DynUnit, weight: &R)

Adds time-diff pair (), weight and value val.

fn push_val_diff_mut(&mut self, val: &mut DynUnit, weight: &mut R)

Adds time-diff pair (), weight and value val.

fn reserve(&mut self, additional: usize)

Allocates room for additional keys.

fn done(self) -> FallbackWSet<K, R>

Completes building and returns the batch.

fn num_keys(&self) -> usize

fn num_tuples(&self) -> usize

fn new_builder(factories: &Output::Factories) -> Self

Creates a new builder with an initial capacity of 0.

fn push_diff(&mut self, weight: &Output::R)

where Output::Time: PartialEq<()>,

Adds time-diff pair (), weight.

fn push_diff_mut(&mut self, weight: &mut Output::R)

where Output::Time: PartialEq<()>,

Adds time-diff pair (), weight.

impl<K, R> SizeOf for FallbackWSetBuilder<K, R>

where K: DataTrait + ?Sized, R: WeightTrait + ?Sized, BuilderInner<K, R>: SizeOf,

fn size_of_children(&self, context: &mut Context)

Gets the size of all “children” owned by this value, not including the size of the value itself.

fn size_of(&self) -> TotalSize

Gets the total size of the current value

fn size_of_with_context(&self, context: &mut Context)

Adds the size of the current value to the given Context, including both the size of the value itself and all of its children
