Struct sdset::multi::OpBuilderByKey

pub struct OpBuilderByKey<'a, T: 'a, U: 'a, F, G, K> where
    F: Fn(&T) -> K,
    G: Fn(&U) -> K,
    K: Ord,  { /* fields omitted */ }

Type used to make a set operation on two slices of different types.

The two functions are used to generate a key that will be used to make the set operation and correlate the two slices values.

Methods

impl<'a, T, U, F, G, K> OpBuilderByKey<'a, T, U, F, G, K> where
    F: Fn(&T) -> K,
    G: Fn(&U) -> K,
    K: Ord, 

pub fn new(base: &'a Set<T>, f: F, g: G) -> Self

Construct a type with two slices.

pub fn from_vec(base: &'a Set<T>, others: Vec<&'a Set<U>>, f: F, g: G) -> Self

Construct it with the content of the given slice.

Note that no other allocation than the one of the vec given in parameter is needed for the construction.

pub fn push(&mut self, set: &'a Set<U>)

Push a new set that will be used for the future set operation.

pub fn add(self, set: &'a Set<U>) -> Self

Add a new set that will be used for the future set operation and consume and return the type.

pub fn difference(self) -> DifferenceByKey<'a, T, U, F, G, K>

Prepare the two slices for the difference set operation.
