Struct sdset::duo::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(a: &'a Set<T>, b: &'a Set<U>, f: F, g: G) -> Self

Construct a type with two slices.

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

Prepare the two slices for the difference set operation.

Trait Implementations
