Trait differential_dataflow::trace::Builder
[−]
[src]
pub trait Builder<K, V, T, R, Output: Batch<K, V, T, R>> { fn new() -> Self; fn with_capacity(cap: usize) -> Self; fn push(&mut self, element: (K, V, T, R)); fn done(self, lower: &[T], upper: &[T], since: &[T]) -> Output; fn extend<I: Iterator<Item = (K, V, T, R)>>(&mut self, iter: I) { ... } }
Functionality for building batches from ordered update sequences.
Required Methods
fn new() -> Self
Allocates an empty builder.
fn with_capacity(cap: usize) -> Self
Allocates an empty builder with some capacity.
fn push(&mut self, element: (K, V, T, R))
Adds an element to the batch.
fn done(self, lower: &[T], upper: &[T], since: &[T]) -> Output
Completes building and returns the batch.
Provided Methods
fn extend<I: Iterator<Item = (K, V, T, R)>>(&mut self, iter: I)
Adds an ordered sequence of elements to the batch.
