Struct FuncData

pub struct FuncData<T, F> { /* private fields */ }

FuncData is a convenient way to box up a &[T]->T style function as one that acts on coordinates instead by wrapping it with a handle to the relevant Data.

Implementations

impl<T, F: Fn(&[&T]) -> T> FuncData<T, F>

pub fn new(f: F, data: Data<T>) -> Self

Creates a new FuncData, from the actual function you want to use plus the dataspace it operates on.

Trait Implementations

impl<T: Hash + PartialEq + 'static, F: Fn(&[&T]) -> T + 'static> Aggregator for FuncData<T, F>

fn aggregate(&self, ks: &[usize]) -> usize

This is an associative, commutative function over points in some dataspace. Accepting more than two points is a hack to allow allocation skipping

fn agg_clone(&self) -> Box<dyn Aggregator>

Clone, jammed into the trait to avoid multitrait problems

impl<T: Clone, F: Clone> Clone for FuncData<T, F>

fn clone(&self) -> FuncData<T, F>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
