[−][src]Struct sdset::duo::DifferenceByKey
Represent the difference set operation that will be applied to two slices of different types.
Examples
use sdset::duo::OpBuilderByKey; use sdset::{SetOperation, Set, SetBuf}; #[derive(Debug, Clone, PartialEq, Eq, PartialOrd, Ord)] struct Foo { a: i32, b: u8 } let a = Set::new(&[ Foo{ a: 1, b: 6 }, Foo{ a: 1, b: 7 }, Foo{ a: 1, b: 8 }, Foo{ a: 2, b: 9 }, Foo{ a: 2, b: 10 }, Foo{ a: 3, b: 10 }, ])?; let b = Set::new(&[1, 3, 4, 5]).unwrap(); // Return the field of Foo that will be used for comparison let f = |x: &Foo| x.a; // directly use the i32 for comparison let g = |x: &i32| *x; let op = OpBuilderByKey::new(a, b, f, g).difference(); let res: SetBuf<Foo> = op.into_set_buf(); assert_eq!(res.as_slice(), &[Foo{ a: 2, b: 9 }, Foo{ a: 2, b: 10 }][..]);
